Expand description
Key that can be encoded to/from SS58.
See https://docs.substrate.io/v3/advanced/ss58/ for information on the codec.
Provided Methods§
sourcefn format_is_allowed(f: Ss58AddressFormat) -> bool
fn format_is_allowed(f: Ss58AddressFormat) -> bool
A format filterer, can be used to ensure that from_ss58check
family only decode for
allowed identifiers. By default just refuses the two reserved identifiers.
