Expand description

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

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 ]ⓘNotable traits for &'_ [u8 ]`impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]`

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

Provided methods

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

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.
