Struct RevocationsList 

pub struct RevocationsList {
    pub version: u32,
    pub this_update: DateTime<Utc>,
    pub next_update: DateTime<Utc>,
    pub expires_at: DateTime<Utc>,
    pub crl_number: u64,
    pub revoked: Vec<RevokedEntry>,
}

The signed revocations list fetched from https://mur.run/revocations.json.

Modeled on TUF’s timestamp.json role. Outer DSSE envelope is stripped during fetch; this struct represents the payload.

Fields

version: u32

this_update: DateTime<Utc>

next_update: DateTime<Utc>

expires_at: DateTime<Utc>

After this timestamp Hub refuses to operate until the list is refreshed.

crl_number: u64

Monotonically increasing counter. Hub rejects any list whose crl_number is ≤ the last accepted value (rollback / clock-rollback defence per spec §7.4.1).

revoked: Vec<RevokedEntry>

Implementations

impl RevocationsList

pub fn parse_and_validate( bytes: &[u8], known_crl: Option<u64>, ) -> Result<Self, MuragentError>

Parse from raw JSON bytes and validate monotonicity + expiry.

known_crl is the crl_number from the last accepted list (or None on first fetch — in which case any validly-signed list is accepted).

pub fn is_expired(&self) -> bool

Returns true if the list’s expires_at is in the past.

pub fn is_package_revoked(&self, manifest_hash: &str) -> bool

Returns true if the given manifest hash appears in the revoked list.

manifest_hash should be the sha256:<hex> string from the manifest.

pub fn is_author_revoked(&self, pubkey: &str) -> bool

Returns true if the given author pubkey is revoked.

pubkey should be the ed25519:<base64> string from the manifest.

pub fn load_cached(mur_home: &Path) -> Option<Self>

Load the locally-cached revocations list from <mur_home>/trust/revocations.json.

Returns None if no cache file exists or if the file cannot be parsed. Callers that only need the cached crl_number should unwrap and read list.crl_number.

pub fn save_cached(&self, mur_home: &Path) -> Result<(), MuragentError>

Atomically write the revocations list to the local cache.

Uses temp-file + rename for crash-safety (same pattern as TrustStore).

Trait Implementations

impl Clone for RevocationsList

fn clone(&self) -> RevocationsList

Performs copy-assignment from source.

impl Debug for RevocationsList

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
