Trait Signer 

pub trait Signer:
    Debug
    + Send
    + Sync {
    // Required methods
    fn sign(&self, data: &[u8]) -> Signature;
    fn public_key(&self) -> PublicKey<'_>;
}

A Signer provides the ability to generate a Signature for provided payload data.

This abstraction decouples the caller from the underlying key type and storage.

Note that the key material used by a Signer instance MUST NOT change for the lifetime of the Signer instance.

Required Methods

fn sign(&self, data: &[u8]) -> Signature

Sign data with this private key.

Signatures are non-deterministic and rely on randomness on the host.

fn public_key(&self) -> PublicKey<'_>

Obtain the PublicKey for this Signer.

Invariant: from the caller’s perspective, a single Signer instance always returns the same PublicKey (key material).
