A trait representing the resolution of a symbol in a file.
This trait is yielded as a trait object to the closure given to the
backtrace::resolve function, and it is virtually dispatched as it’s
unknown which implementation is behind it.
A symbol can give contextual information about a function, for example the
name, filename, line number, precise address, etc. Not all information is
always available in a symbol, however, so all methods return an
Returns the name of this function.
The returned structure can be used to query various properties about the symbol name:
Displayimplementation will print out the demangled symbol.
- The raw
strvalue of the symbol can be accessed (if it’s valid utf-8).
- The raw bytes for the symbol name can be accessed.
Returns the starting address of this function.
Returns the file name where this function was defined.
This is currently only available when libbacktrace is being used (e.g.
unix platforms other than OSX) and when a binary is compiled with
debuginfo. If neither of these conditions is met then this will likely
Returns the line number for where this symbol is currently executing.
This return value is typically
is consequently subject to similar caveats.
type Error = Infallible
The type returned in the event of a conversion error.
