Function backtrace::resolve_unsynchronized 
source · pub unsafe fn resolve_unsynchronized<F>(addr: *mut c_void, cb: F)where
    F: FnMut(&Symbol),Expand description
Same as resolve, 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
function for more documentation and examples.

See information on resolve for caveats on cb panicking.
