[dependabot]

Bumps cpp_demangle from 0.4.4 to 0.5.1.

Changelog

Sourced from cpp_demangle's changelog.

0.5.1

Released 2025/11/5

Added

• Fold expressions are supported. (#303)[https://redirect.github.com/Support fold expressions gimli-rs/cpp_demangle#303]

Fixed

• We are now less conservative when accepting the legacy production for increased compatibility with libiberty.

• When printing conversion and cast operators we now treat the type we are converting/casting to as a self-contained child and prevent outer template parameters/etc from leaking into it.

• When looking for a <template-template-param> production after a conversion operator, we now correctly handle the case where peeking for the next character fails because we reached the end of the symbol.

• When parsing <unqualified-name productions, accept both with and without an "on" prefix. LLVM requires the prefix, while libiberty accepts but does not require it.

• Empty braced-enclosed initializer lists are now accepted.

0.5.0

Released 2025/9/23

Added

Changed

Removed

• The implementation of Display for Symbol has been removed. This implementation violated the contract of the Display trait by potentially returning an Err without a failure of a write to the provided stream. This contract is enforced by assertion since Rust 1.80.0. The new Symbol::demangle function is the intended replacement for uses of

Looks like cpp_demangle is up-to-date now, so this is no longer needed.
