RLM uses a ports-and-adapters (hexagonal) architecture: //! - **Core**: Execution logic, events, types (this crate) //! - **Ports**: Traits for REPL, LLM, event sinks //! - **Adapters**: Concrete implementations (other crates) +//! +//! ## Key Components +//! +//! ### High-Level Client API +//! +//! The [`RlmExecutor`] provides the core execution interface: +//! +//! ```rust,no_run +//! # use rlm_core::{RlmExecutor, RlmRequest, RlmConfig}; +//! # use std::sync::Arc; +//! # async fn example(executor: RlmExecutor>, Arc>) -> rlm_core::RlmResult<()> { +//! // Create a request +//! let request = RlmRequest { +//! query: "What is 2+2?".to_string(), +//! context: None, +//! max_iterations: 5, +//! recursion_depth: 2, +//! // ... other fields +//! }; +//! +//! // Execute with event sink +//! // let response = executor.execute(request, event_sink).await?; +//! # Ok(()) +//! # } +//! ``` +//! +//! ### Builder Pattern +//! +//! All major components use builder patterns for configuration: +//! +//! ```rust,no_run +//! use rlm_core::RlmConfig; +//! +//! // Configure RLM for different scenarios +//! let config = RlmConfig::new() +//! .with_max_context_length(500_000) +//! .with_recursion_depth(5); +//! +//! # Ok::<(), rlm_core::RlmError>(()) +//! ``` +//! +//! ### Context Processing +//! +//! RLM handles large contexts efficiently through intelligent chunking: +//! +//! ```rust,no_run +//! use rlm_core::{ContextAnalyzer, ContextAnalysisConfig}; +//! +//! // Configure context analysis +//! let config = ContextAnalysisConfig::new() +//! .with_max_chunk_size(16384) +//! .with_semantic_chunking(true); +//! +//! let analyzer = ContextAnalyzer::new(config); +//! let chunks = analyzer.analyze_context("large document content...", None).await?; +//! # Ok::<(), rlm_core::RlmError>(()) +//! ``` +//! +//! ### Session Management +//! +//!

[Async & Performance Patterns](#async--performance-patterns) +6. [Documentation & Testing](#documentation--testing) +7. [Code Generation Guidelines](#code-generation-guidelines) + +--- + +## Core Design Principles + +### Idiomatic +- Follow Rust API Guidelines and naming conventions +- Use snake_case for functions/variables, PascalCase for types +- Embrace the ecosystem with its strengths and weaknesses +- Write code that feels natural to Rust developers + +### Consistent +- Client libraries should be consistent within Rust's ecosystem +- Use familiar patterns from std and popular crates +- Service-agnostic concepts (logging, HTTP, errors) should be uniform +- Maintain feature parity across API versions + +### Approachable +- Provide great documentation with examples +- Use predictable defaults implementing best practices +- Make common use cases easily discoverable +- Progressive concept disclosure (simple โ†’ advanced) + +### Diagnosable +- Make network calls discoverable and predictable +- Provide actionable, human-readable error messages +- Support standard debugging tools and logging +- Clear error correlation with service responses + +### Dependable +- Breaking changes are extremely harmful +- Never introduce incompatibilities without strong justification +- Avoid dependencies that force compatibility issues +- Follow semantic versioning strictly + +--- + +## API Design Standards + +### Naming Conventions + +#### Method Names + +| Pattern | Parameters | Usage | Examples | +|---------|-----------|--------|----------| +| `new` | No self, โ‰ฅ1 args | Constructor | `Client::new(endpoint, creds)` | +| `with_*` | No self, โ‰ฅ1 args | Alternative constructors | `Client::with_connection_string()` | +| `from_*` | 1 arg | Conversion constructor | `Config::from_env()` | +| `as_*` | `&self` | Free conversion/view | `data.as_bytes()` | +| `to_*` | `&self` | Expensive conversion | `str.to_string()` | +| `into_*` | `self` (consumes) | Consuming conversion | `response.into_body()` | +| `is_*` | `&self` | Boolean check | `result.is_ok()` | +| `has_*` | `&self` | Boolean check | `request.has_body()` | + +#### CRUD Operations + +| Pattern | HTTP Method | Behavior | Example | +|---------|------------|----------|---------| +| `add_*` | POST/PUT | Add to collection, fail if exists | `add_user(user)` | +| `delete_*` | DELETE | Delete resource, don't fail if missing | `delete_user(id)` | +| `get_*` | GET | Get resource, fail if missing | `get_user(id)` | +| `list_*` | GET | Get collection (may be paged) | `list_users()` | +| `*_exists` | GET/HEAD | Check existence | `user_exists(id)` | +| `set_*` | POST/PUT | Add or update | `set_user(user)` | +| `update_*` | PATCH/PUT | Update existing, fail if missing | `update_user(id, data)` | + +#### Client Naming + +```rust +// โœ… DO: Service-specific client names with Client suffix +pub struct

It extracts documentation from special comments in your source code. + +#### Documentation Comments + +```rust +/// This is a doc comment for the item that follows +/// +/// # Examples +/// +/// ``` +/// use my_crate::foo; +/// +/// let result = foo(42); +/// assert_eq!(result, 84); +/// ``` +pub fn foo(x: i32) -> i32 { + x * 2 +} + +//! This is an inner doc comment for the containing item (e.g., module or crate) +//! +//! Use this at the top of lib.rs to document your entire crate. +``` + +#### Building Documentation + +```bash +# Build documentation for your crate +cargo doc + +# Build and open in browser +cargo doc --open + +# Include private items +cargo doc --document-private-items + +# Build documentation for all dependencies +cargo doc --no-deps # Opposite: only your crate + +# Build for specific features +cargo doc --features "feature1,feature2" + +# Build with all features enabled +cargo doc --all-features +``` + +#### Output Location + +Documentation is generated in `target/doc/[crate_name]/index.html` + +### Documentation Sections + +Every well-documented item should include: + +#### 1. Summary Line + +```rust +/// Computes the factorial of a number using iterative algorithm. +``` + +First line should be a concise summary (appears in search results). + +#### 2. Extended Description + +```rust +/// Computes the factorial of a number using iterative algorithm. +/// +/// This implementation uses an iterative approach rather than recursion +/// to avoid stack overflow for large values. Returns `None` if the +/// result would overflow `u64`. +``` + +#### 3. Examples Section + +```rust +/// # Examples +/// +/// Basic usage: +/// +/// ``` +/// use my_crate::factorial; +/// +/// assert_eq!(factorial(5), Some(120)); +/// assert_eq!(factorial(0), Some(1)); +/// ``` +/// +/// Handling overflow: +/// +/// ``` +/// # use my_crate::factorial; +/// assert_eq!(factorial(100), None); // Would overflow +/// ``` +``` + +**Note**: Lines starting with `#` in code blocks are compiled but hidden in docs. + +#### 4. Errors Section + +```rust +/// # Errors +/// +/// Returns `Err` if: +/// +/// - The file does not exist +/// - The process lacks permissions to read the file +/// - The file contains invalid UTF-8 +``` + +#### 5. Panics Section + +```rust +/// # Panics +/// +/// Panics if the index is out of bounds. +``` + +#### 6. Safety Section (for unsafe functions) + +```rust +/// # Safety +/// +/// The caller must ensure that: +/// +/// - The pointer is valid and properly aligned +/// - The data behind the pointer is initialized +/// - No other references exist to the same memory +``` + +### Doc Attributes + +```rust +// Link to other items +/// See also: [`Config`], [`Client::connect`] + +// Hide implementation details +#[doc(hidden)] +pub struct InternalHelper; + +// Inline documentation from another item +#[doc(inline)] +pub use some_module::ImportantType; + +// Configure documentation +#![doc(html_logo_url = "https://example.com/logo.png")] +#![doc(html_favicon_url = "https://example.com/favicon.ico")] +#![doc(html_root_url = "https://docs.rs/my-crate/0.1.0")] +``` + +### Intra-doc Links + +Use backticks for inline code and square brackets for links: + +```rust +/// This uses the [`Config`] struct and calls [`Client::connect`]. +/// +/// You can also link to modules: [`crate::utils`] +/// External crates: [`std::fs::File`] +/// Methods: [`Vec::push`] +/// Associated items: [`Option::Some`] +``` + +### Documentation Tests + +Code blocks in documentation are automatically tested: + +```rust +/// ``` +/// let x = 5; +/// assert_eq!(x, 5); +/// ``` +``` + +Control test behavior: + +```rust +/// ```no_run +/// // This code is compiled but not run +/// std::process::exit(0); +/// ``` + +/// ```ignore +/// // This code is not compiled or run +/// This is not valid Rust +/// ``` + +/// ```should_panic +/// // This test should panic +/// panic!("expected"); +/// ``` + +/// ```compile_fail +/// // This should fail to compile +/// let x: i32 = "not a number"; +/// ``` +``` + +### Cargo.toml Metadata for Documentation + +```toml +[package] +name = "my-crate" +version = "0.1.0" +authors = ["Your Name "] +edition = "2021" +description = "A brief description of what your crate does" +documentation = "https://docs.rs/my-crate" # Optional: only if not using docs.rs +homepage = "https://my-crate.com" # Optional: project website +repository = "https://github.com/username/my-crate" +readme = "README.md" +keywords = ["keyword1", "keyword2"] # Max 5 keywords +categories = ["category1"] # See https://crates.io/categories +license = "MIT OR Apache-2.0" + +# Enable all features when building docs +[package.metadata.docs.rs] +all-features = true +rustdoc-args = ["--cfg", "docsrs"] +``` + +### Conditional Documentation + +```rust +// Code only included in documentation +#[cfg(doc)] +use std::collections::HashMap; + +// Code excluded from documentation +#[cfg(not(doc))] +use fast_hashmap::HashMap; + +// Detect docs.rs specifically +#[cfg(docsrs)] +mod extra_docs; +``` + +--- + +## Automatic Publishing to docs.rs + +### How docs.rs Works + +1. **Automatic Builds**: When you publish to crates.io, docs.rs automatically builds your documentation +2. **Queue System**: Crates are built in order; check the [build queue](https://docs.rs/releases/queue) +3. **Multiple Targets**: Documentation is built for multiple platforms by default +4. **Free Hosting**: All documentation is hosted permanently at `https://docs.rs/[crate-name]` + +### Configuring docs.rs Builds + +Add configuration to `Cargo.toml`: + +```toml +[package.metadata.docs.rs] +# Features to enable during docs.rs build (default: []) +features = ["feature1", "feature2"] + +# Build with all features (default: false) +all-features = true + +# Build without default features (default: false) +no-default-features = true + +# Default target platform (default: "x86_64-unknown-linux-gnu") +default-target = "x86_64-unknown-linux-gnu" + +# Additional targets to build documentation for +# Default targets are automatically built: +# - x86_64-unknown-linux-gnu +# - aarch64-apple-darwin +# - x86_64-pc-windows-msvc +# - aarch64-unknown-linux-gnu +# - i686-pc-windows-msvc +targets = ["wasm32-unknown-unknown"] + +# Or add targets without removing defaults +additional-targets = ["i686-apple-darwin"] + +# Additional rustc flags +rustc-args = ["--cfg", "my_cfg"] + +# Additional rustdoc flags +rustdoc-args = ["--cfg", "docsrs", "--html-in-header", "docs-header.html"] + +# Additional cargo arguments (options only, not subcommands) +cargo-args = ["-Z", "build-std"] +``` + +### Detecting docs.rs Environment + +In Rust code: + +```rust +#[cfg(docsrs)] +pub mod docs_only_module { + //!

Caching + + Implement multi-level caching to reduce redundant computations: + + - **Memory caching**: For frequently accessed data + - **Distributed caching**: For shared data across instances + - **CDN caching**: For static assets and content + + ### 2. Parallel Processing + + Utilize parallel processing for CPU-intensive tasks: + + - **Thread pools**: For concurrent task execution + - **Async operations**: For I/O-bound operations + - **Worker queues**: For background processing + + ### 3. Data Optimization + + Optimize data structures and algorithms: + + - **Efficient data structures**: Choose appropriate collections + - **Algorithm complexity**: Minimize time and space complexity + - **Data compression**: Reduce memory and network overhead + + ### 4. Monitoring and Profiling + + Continuous monitoring is essential for performance optimization: + + - **Performance metrics**: Track response times, throughput + - **Resource utilization**: Monitor CPU, memory, disk usage + - **Error rates**: Track and analyze failure patterns + + ## Implementation Examples + + ### Caching Implementation + + ```rust + use std::collections::HashMap; + use tokio::sync::RwLock; + + pub struct Cache { + data: RwLock>, + ttl: std::time::Duration, + } + + impl Cache + where + K: Eq + std::hash::Hash + Clone, + V: Clone, + { + pub async fn get(&self, key: &K) -> Option { + let cache = self.data.read().await; + cache.get(key).cloned() + } + + pub async fn set(&self, key: K, value: V) { + let mut cache = self.data.write().await; + cache.insert(key, value); + } + } + ``` + + ### Parallel Processing Example + + ```rust + use tokio::task::JoinSet; + + pub async fn process_in_parallel( + items: Vec, + processor: impl Fn(T) -> BoxFuture> + Send + Sync + 'static, + ) -> Result<(), Error> { + let mut join_set = JoinSet::new(); + + for item in items { + join_set.spawn(processor(item)); + } + + while let Some(result) = join_set.join_next().await { + result??; + } + + Ok(()) + } + ``` + + ## Best Practices + + 1. **Profile before optimizing**: Always measure first + 2. **Focus on bottlenecks**: Optimize the slowest parts first + 3. **Test thoroughly**: Ensure optimizations don't break functionality + 4. **Monitor continuously**: Track performance over time + 5. **Document changes**: Keep records of optimization efforts + + ## Common Pitfalls + + - **Premature optimization**: Optimizing before identifying bottlenecks + - **Over-engineering**: Adding unnecessary complexity + - **Ignoring trade-offs**: Every optimization has costs + - **Not measuring impact**: Failing to verify optimization benefits + + ## Conclusion + + Performance optimization is an ongoing process that requires careful analysis, + methodical implementation, and continuous monitoring.

Essential for production deployment. + +**Independent Test**: Can be tested by making requests while monitoring logs and metrics endpoints to verify comprehensive observability data is captured and properly structured. + +**Acceptance Scenarios**: + +1. **Given** active RLM processing, **When** recursive calls are made, **Then** structured logs capture call depth, token counts, and processing
