Function backtrace::resolve_frame_unsynchronized 
source · pub unsafe fn resolve_frame_unsynchronized<F>(frame: &Frame, cb: F)where
    F: FnMut(&Symbol),Expand description
Same as resolve_frame, only unsafe as it’s unsynchronized.
This function does not have synchronization guarantees but is available
when the std feature of this crate isn’t compiled in. See the
resolve_frame function for more documentation and examples.

See information on resolve_frame for caveats on cb panicking.
