Module signer

Abstractions and implementations for transaction signers.

Modules

• keypair
• null_signer
• presigner
• signers

Enums

• SignerError

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)
