Module r0_9_0 

Release 0.9.0 (2025-11-05)

Breaking changes

• MSRV has been increased to 1.88.0;
• This release adds a std feature. Most functionality remains available with this feature disabled, but anything involving OsStr, OsString, Path or PathBuf is only available with std feature enabled. If you are depending on libloading with no-default-features set to true, you may see compilation errors. Running with std feature enabled is still the strongly recommended option. no-std functionality has been contributed in #184;
• As a result of the change above, functions that previously using AsRef<OsStr> to describe the library path now require an implementor of AsFilename instead. AsFilename has been implemented for the most likely types used previously. Please file an issue if you rely on a type that no longer works.
• The Error enum’s variants changed in incompatible ways. Furthermore it has been changed to return the underlying dlerror via the source method (matching behaviour on Windows.)
• On Windows providing filenames with interior null bytes to Library::open and related functions will now report an error instead of silently truncating the provided input. This is a bug fix.

Non-breaking changes

• Symbol lookups via Library::get and related functions can now use a wider variety of string types, including &CStr. This, among other things, means that c"symbol" literals can be used without incurring any additional null-byte checking overhead or reallocations that were necessary for &[u8] argument used previously to support b"literals". &[u8] is still accepted. This new functionality has been contributed in #174 and #184.
