Struct Registry 

pub struct Registry { /* private fields */ }

Known public keys, indexed by actor id. This is the verification side’s whole world: an unregistered key is an unknown author.

Implementations

impl Registry

pub fn new() -> Self

Creates an empty registry.

pub fn register( &mut self, public_key_bytes: &[u8; 32], ) -> Result<ContentHash, IdentityError>

Registers a public key and returns the actor id it now answers to.

Errors

Returns IdentityError::BadKey when the bytes are not a valid ed25519 public key.

pub fn verify_entry( &self, entry: &OpEntry, ) -> Result<ContentHash, IdentityError>

Verifies entry’s author signature and returns the author’s id.

Errors

IdentityError::Unsigned for a missing signature, IdentityError::UnknownKey for an unregistered author, and IdentityError::BadSignature when the signature does not match the entry (tampered entry or wrong key).

pub fn verify_submission( &self, channel: &str, payload: &[u8], sig: &Witness, ) -> Result<ContentHash, IdentityError>

Verifies a signature over submission content — the sequencer-side check before a position is assigned. Returns the author’s id.

Errors

Same failure modes as Registry::verify_entry, minus IdentityError::Unsigned.

pub fn verify_signing_hash( &self, signing: &ContentHash, sig: &Witness, ) -> Result<ContentHash, IdentityError>

Same check, for a caller that has already computed the submission’s choir_oplog::signing_hash — an admission policy that indexes submissions by it, for instance. Hashing the same bytes twice per op is measurable on the write path, and the node’s allocation budget is the test that says so.

Errors

Same failure modes as Registry::verify_submission.

Trait Implementations

impl Default for Registry

fn default() -> Registry

Returns the “default value” for a type.
