0.2.174→0.2.190Release Notes
rust-lang/libc (libc)
v0.2.190Compare Source
There is now a single config for enabling 64-bit
time_t:libc_unstable_time64. This can be setunconditionally; it opts in to 64-bit
time_ton the following platforms that use 32-bit bydefault:
musl v1.2.
Most other 32-bit platforms are either already using 64-bit
time_t, or are considered legacyand will not be gaining support from their upstream maintainers.
You can enable this using
RUSTFLAGS:RUSTFLAGS='--cfg=libc_unstable_time64' cargo ...Note that there may still be some changes to features gated by this config option, hence "unstable"
in its name. In the near future we will rename it to just
libc_time64. Until then, please test itout and report any bugs you find!

This release contains a number of improvements related to 64-bit
time_tconfiguration.Of note the existing
RUST_LIBC_UNSTABLE_*environment variables have been replacedwith configuration options. The new way to use these is:
Being able to set this via
RUSTFLAGSmakes it easier to only apply configuration tospecific targets (and notably, not the host if build scripts are used).
There are two other notable changes:
The 32-bit
windows-gnutargets now respectlibc_unstable_gnu_time_bitsuClibc now supports a similar configuration option:
RUSTFLAGS='--cfg=libc_unstable_uclibc_time64'As a reminder, these options are under active development and may change in the future
(hence the "unstable" in the name). It likely that we will harmonize everything under a
single configuration option before considering them stable.

With this release, we now have unstable support for 64-bit
time_ton 32-bitplatforms with both Musl and Glibc. Testing is appreciated!
For now, these can be enabled by setting environment variables during build:
Note that the exact configuration will change in the future. Setting the
MUSL_V1_2_3variable also enables some newer API unrelated totime_t.Added
