Expand description

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

Required Associated Types§

source

type KeyTypeIdProviders

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

Required Methods§

source

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

Return the key-type IDs supported by this set.

source

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

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

Provided Methods§

source

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

Get the decoded key with key-type ID i.

source

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.
