Expand description

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

Associated Types

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

Required methods

Return the key-type IDs supported by this set.

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

Provided methods

Get the decoded key with key-type ID i.

Verify a proof of ownership for the keys.
