Module std::backtrace_rs::backtrace::libunwind
source · Expand description
Backtrace support using libunwind/gcc_s/etc APIs.
This module contains the ability to unwind the stack using libunwind-style APIs. Note that there’s a whole bunch of implementations of the libunwind-like API, and this is just trying to be compatible with most of them all at once instead of being picky.
The libunwind API is powered by _Unwind_Backtrace and is in practice very
reliable at generating a backtrace. It’s not entirely clear how it does it
(frame pointers? eh_frame info? both?) but it seems to work!
Most of the complexity of this module is handling the various platform differences across libunwind implementations. Otherwise this is a pretty straightforward Rust binding to the libunwind APIs.
This is the default unwinding API for all non-Windows platforms currently.
