A minimal deserializer for inspecting std::backtrace::Backtrace's Debug format.
For the time being, the rust standard library is exporting the smallest API
surface for std::backtrace::Backtrace that it possibly can, and only allows
inspection via the Debug and Display traits. However, in order to provide
custom formatting for backtraces, libraries like color-backtrace need to be
able to iterate over the frames of a backtrace and access its various members
like the filename and line number.
This library provides a stop-gap solution. Until std eventually exports a
stable iterator interface to backtrace frames this library will attempt to
provide best effort parsing of backtrace's unstable Debug output. This will
allow libraries like color-backtrace to provide unstable support for
std::backtrace::Backtrace until it eventually stabilizes.
Once std eventually stabilizes this library will update the internals to depend upon the provided iterator API instead of potentially fragile parsing.
