Struct Signer 

pub struct Signer { /* private fields */ }

An Ed25519 signer. Construct from a 32-byte seed via Signer::from_seed_bytes. Real-world callers should generate the seed from an OS-level CSPRNG (getrandom, rand_core::OsRng, …).

Implementations

impl Signer

pub fn from_seed_bytes(seed: [u8; 32]) -> Self

Build a signer from a 32-byte Ed25519 seed.

The seed is NOT hashed or stretched; pass a uniformly random value from a secure RNG. Deterministic seeds are fine for tests and smoke demos; use real entropy in production.

pub fn public_key_bytes(&self) -> [u8; 32]

The 32-byte Ed25519 public key associated with this signer.

pub fn sign_commit(&self, commit: &mut Commit) -> Result<(), Error>

Sign a Commit in place.

Clears any existing signature, canonicalises the Commit, signs the bytes, and attaches the resulting Signature.

Errors

Codec errors while canonicalising.

pub fn sign_operation(&self, op: &mut Operation) -> Result<(), Error>

Sign an Operation in place. Same protocol as sign_commit.

Errors

Codec errors while canonicalising.
