pub fn lookup_path(path: &DerivationPath) -> Option<u8>Expand description
Look up DerivationPath → standard-table indicator. Returns None
if the path is not in the dictionary (encoder falls through to
explicit-path encoding). Comparison is structural (parses each
table entry to a DerivationPath); this avoids the m/-prefix
pitfall in bitcoin::bip32::DerivationPath’s Display.
