Crate symbolic::demangle

source ·
Expand description

Demangling support for various languages and compilers.

Currently supported languages are:

  • C++ (GCC-style compilers and MSVC) (features = ["cpp", "msvc"])
  • Rust (both legacy and v0) (features = ["rust"])
  • Swift (up to Swift 5.3) (features = ["swift"])
  • ObjC (only symbol detection)

As the demangling schemes for the languages are different, the supported demangling features are inconsistent. For example, argument types were not encoded in legacy Rust mangling and thus not available in demangled names. The demangling results should not be considered stable, and may change over time as more demangling features are added.

This module is part of the symbolic crate and can be enabled via the demangle feature.

Examples

use symbolic_common::{Language, Name};
use symbolic_demangle::{Demangle, DemangleOptions};

let name = Name::from("__ZN3std2io4Read11read_to_end17hb85a0f6802e14499E");
assert_eq!(name.detect_language(), Language::Rust);
assert_eq!(
    name.try_demangle(DemangleOptions::complete()),
    "std::io::Read::read_to_end"
);
