Expand description

Common trait for memory signers.

Required Methods§

fn random(rng: &mut impl TryCryptoRng) -> Result<Self, Error>
where Self: Sized,

Create a new random signer.

fn new_from_seed(seed: &[u8]) -> Result<Self, Error>
where Self: Sized,

Create a new signer from the given seed.

fn from_bytes(bytes: &[u8]) -> Result<Self, Error>
where Self: Sized,

Recreate signer from a byte serialization.

fn to_bytes(&self) -> Vec<u8> ⓘ

Serialize the signer into bytes.

fn public_key(&self) -> PublicKey

Return the public key counterpart to the signer’s secret key.

fn sign(&self, context: &[u8], message: &[u8]) -> Result<Signature, Error>

Generate a signature over the context and message.

fn sign_raw(&self, message: &[u8]) -> Result<Signature, Error>

Generate a signature over the message.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
