Traits

EncodableKey

The EncodableKey trait defines the interface by which cryptographic keys/keypairs are read, written, and derived from sources.

EncodableKeypair

The EncodableKeypair trait extends EncodableKey for asymmetric keypairs, i.e. have associated public keys.

SeedDerivable

The SeedDerivable trait defines the interface by which cryptographic keys/keypairs are derived from byte seeds, derivation paths, and passphrases.

Signer

The Signer trait declares operations that all digital signature providers must support. It is the primary interface by which signers are specified in Transaction signing interfaces

Functions

unique_signers

Removes duplicate signers while preserving order. O(n²)
