Function suffixes

pub fn suffixes(path: &str, fmt: PathFormat) -> Vec<String>

Expand description

Get all suffixes (like Python’s PurePath.suffixes). “file.tar.gz” → [“.tar”, “.gz”] Get all suffixes (extensions) of the file name.

Matches Python pathlib’s algorithm:

  name = self.name
  if name.endswith('.'):
      return []
  name = name.lstrip('.')
  return ['.' + suffix for suffix in name.split('.')[1:]]

Notable corollaries:

Trailing-dot names have no suffixes (foo. → []).
Names that consist entirely of leading dots (., .., ...) yield [] because lstrip('.') produces the empty string.
.tar.gz (a name that is itself a suffix-looking filename) yields ['.gz'], not ['.tar', '.gz'] — the leading-dot prefix is stripped before splitting.
..foo yields [] even though suffix returns .foo, because lstrip('.') produces 'foo' which has no inner dot. This is a pathlib quirk we preserve for parity.
