Implementations

impl RegistryCheckpoint

pub fn build( registry: &Registry, draft: CheckpointDraft, signing_key: &SigningKey, ) -> Result<Self, String>

Build a checkpoint over a registry, signing it with the supplied hub-operator key. The signature covers the canonical preimage of the checkpoint body with signature and checkpoint_id zeroed; the checkpoint_id is then derived from the signed preimage (so two checkpoints with identical body + signature share the same id, and a tampered signature surfaces as a hash mismatch).

pub fn preimage_bytes(&self) -> Result<Vec<u8>, String>

Canonical preimage bytes for the signature. Excludes signature and checkpoint_id so the preimage is derivable from the rest of the body alone.

pub fn derive_id(&self) -> Result<String, String>

Content-addressed id over the (signed) body, including the signature so a tampered signature surfaces as an id mismatch.

pub fn verify(&self, registry: &Registry) -> Result<(), String>

Verify the checkpoint: re-derive the id and assert match, re-compute the registry root and assert match, verify the Ed25519 signature against signer_pubkey.

Trait Implementations

impl Clone for RegistryCheckpoint

fn clone(&self) -> RegistryCheckpoint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RegistryCheckpoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RegistryCheckpoint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RegistryCheckpoint

fn eq(&self, other: &RegistryCheckpoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RegistryCheckpoint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
