Introduces error codes, improved documentation, and expanded test coverage.

Features

• Error Code Support:
  • Added .code property to both Ok and Err classes.
  • Default codes: 0 for Ok, 1 for Err.
  • Custom error codes can be provided when constructing Err.

Documentation

• Updated README with:
  • Project status, version, and license badges.
  • Examples showing how to use error codes in pattern matching.
  • Clearer explanation of unwrap_value and unwrap_error.

Tests

• Added unit tests for .code property:
  • Ensures default values (0 for Ok, 1 for Err).
  • Validates custom error codes.
• Expanded test coverage for unwrap_value and unwrap_error.

Chores

• Removed commit message generation instructions.
• Bumped version to 0.2.0.

Breaking Changes

v0.1.0

0.1.0 (2025-11-16)

First release.

Features

• Result Type Pattern Implementation:

  • Ok[T] - Represents successful values with type safety
  • Err[E] - Represents error values with exception constraints
  • Result[T, E] - Type alias for union of Ok and Err types

• Core Functionality:

  • .value property - Access the wrapped value (Ok) or None (Err)
  • .error property - Access the wrapped error (Err) or None (Ok)
  • .unwrap_value() method - Extract value or raise UnwrapError if Err
  • .unwrap_error() method - Extract error or raise UnwrapError if Ok

• Python Integration:

  • Proper __repr__, __eq__, __ne__, __hash__ implementations
  • Boolean evaluation (Ok is truthy, Err is falsy)
  • Pattern matching support via __match_args__
  • isinstance helper with ResultOption tuple

• Error Handling:

  • Custom UnwrapError exception for unwrap operations
  • Proper exception chaining for Err unwrap_value calls
  • Access to original Result via .result property on UnwrapError

• Memory Efficiency:

  • __slots__ optimization for reduced memory footprint
  • Minimal object overhead with single _value slot per instance
