Crate crate_name_utils

Utility functions for parsing and processing crate names in symbol strings.

Functions

• crate_name_from_path
  Returns the crate name that is derived from a crate object file path.
• get_containing_crate_name
  Parses the given symbol string to try to find the name of the parent crate that contains the symbol. Depending on the symbol, there may be multiple potential parent crates; if so, they are returned in order of likeliness: the first crate name in the symbol is most likely to contain it. If the parent crate cannot be determined (e.g., a no_mangle symbol), then an empty Vec is returned.
• get_containing_crate_name_ranges
  Same as get_containing_crate_name(), but returns the substring Ranges of where the parent crate names are located in the given demangled_full_symbol string.
• is_valid_crate_name_char
  Crate names must be only alphanumeric characters, an underscore, or a dash.
• replace_containing_crate_name
  Replaces the old_crate_name substring in the given demangled_full_symbol with the given new_crate_name, if it can be found, and if the parent crate name matches the old_crate_name. If the parent crate name can be found but does not match the expected old_crate_name, then None is returned.
