Module libloading::changelog::r0_6_0

Release 0.6.0 (2020-04-05)

• Introduced a new method os::unix::Library::get_singlethreaded;
• Added (untested) support for building when targeting Redox and Fuchsia;
• The APIs exposed by this library no longer panic and instead return an Err when it used to panic.

Breaking changes

• Minimum required (stable) version of Rust to build this library is now 1.40.0;

• This crate now implements a custom Error type and all APIs now return this type rather than returning the std::io::Error;

• libloading::Result has been removed;

• Removed the dependency on the C compiler to build this library on UNIX-like platforms. libloading used to utilize a snippet written in C to work-around the unlikely possibility of the target having a thread-unsafe implementation of the dlerror function. The effect of the work-around was very opportunistic: it would not work if the function was called by forgoing libloading.

  Starting with 0.6.0, Library::get on platforms where dlerror is not MT-safe (such as FreeBSD, DragonflyBSD or NetBSD) will unconditionally return an error when the underlying dlsym returns a null pointer. For the use-cases where loading null pointers is necessary consider using os::unix::Library::get_singlethreaded instead.
