Struct IncrementalSigner 

pub struct IncrementalSigner { /* private fields */ }

Multi-part (incremental) interface for SigningKeyPair.

Implementations

impl IncrementalSigner

pub fn new() -> Self

Returns a new incremental signer instance.

pub fn update<Message: Bytes>(&mut self, message: &Message)

Updates the state for this incremental signer with message.

pub fn finalize<Signature: NewByteArray<CRYPTO_SIGN_BYTES>, SecretKey: ByteArray<CRYPTO_SIGN_SECRETKEYBYTES>>( self, secret_key: &SecretKey, ) -> Result<Signature, Error>

Finalizes this incremental signer, returning the signature upon success.

Errors

The fixed-size signature and secret-key types satisfy the current implementation’s requirements, so this function does not return an error for valid type implementations. The Result is retained for compatibility with the underlying signing API.

pub fn verify<Signature: ByteArray<CRYPTO_SIGN_BYTES>, PublicKey: ByteArray<CRYPTO_SIGN_PUBLICKEYBYTES>>( self, signature: &Signature, public_key: &PublicKey, ) -> Result<(), Error>

Verifies signature as a valid signature for this signer.

Errors

Returns an error if signature is not valid for the accumulated message and public_key.

Trait Implementations

impl Default for IncrementalSigner

fn default() -> Self

Returns the “default value” for a type.
