Crate rustc_demangle
source ·Expand description
Demangle Rust compiler symbol names.
This crate provides a demangle
function which will return a Demangle
sentinel value that can be used to learn about the demangled version of a
symbol name. The demangled representation will be the same as the original
if it doesn’t look like a mangled symbol name.
Demangle
can be formatted with the Display
trait. The alternate
modifier (#
) can be used to format the symbol name without the
trailing hash value.
Examples
use rustc_demangle::demangle;
assert_eq!(demangle("_ZN4testE").to_string(), "test");
assert_eq!(demangle("_ZN3foo3barE").to_string(), "foo::bar");
assert_eq!(demangle("foo").to_string(), "foo");
// With hash
assert_eq!(format!("{}", demangle("_ZN3foo17h05af221e174051e9E")), "foo::h05af221e174051e9");
// Without hash
assert_eq!(format!("{:#}", demangle("_ZN3foo17h05af221e174051e9E")), "foo");
Structs
- Representation of a demangled symbol name.
- Error returned from the
try_demangle
function below when demangling fails.
Functions
- De-mangles a Rust symbol into a more readable version
- Process a stream of data from
input
into the providedoutput
, demangling any symbols found within. - The same as
demangle
, except return anErr
if the string does not appear to be a Rust symbol, rather than “demangling” the given string as a no-op.
