Expand description

Opaque data type that may be destructured into a series of raw byte slices (which represent individual keys).

Required Associated Types§

type KeyTypeIdProviders

Types bound to this opaque keys that provide the key type ids returned.

Required Methods§

fn key_ids() -> &'static [KeyTypeId]

Return the key-type IDs supported by this set.

fn get_raw(&self, i: KeyTypeId) -> &[u8] ⓘ

Get the raw bytes of key with key-type ID i.

Provided Methods§

fn get<T>(&self, i: KeyTypeId) -> Option<T>
where T: Decode,

Get the decoded key with key-type ID i.

fn ownership_proof_is_valid(&self, _proof: &[u8]) -> bool

Verify a proof of ownership for the keys.

Object Safety§

This trait is not object safe.
