Class Method Summary

• .cache_size : Int32

  Returns the number of cached demangled symbols.

• .clean_crystal_symbol(symbol : String) : String

  Cleans Crystal mangled names for human-readable display

• .clear_cache : Nil

  Clears the demangling cache.

• .decode_pdb_escapes(symbol : String) : String

  Decodes LLVM/MSVC PDB hex escapes such as: _2A.

• .demangle(symbol : String, client : Transport::Base | Nil = nil) : String

  Demangles a symbol name.

• .is_crystal_symbol?(symbol : String) : Bool

  Checks if symbol matches common Crystal mangled symbol conventions

• .is_mangled_native?(symbol : String) : Bool

  Checks if symbol looks like Itanium (_Z...) or MSVC (?...) mangled C++

• .parse_crystal_method(symbol : String) : Tuple(String, String, Bool) | Nil

  Parses a cleaned or mangled Crystal symbol into {class_name, method_name, is_instance_method} Returns nil if the symbol cannot be decomposed into a Crystal class and method.

• .strip_r2_prefixes(symbol : String) : String

  Strips common radare2 symbol prefixes (sym.imp., sym., pdb., sym.pdb.)
