RevocationView

Struct RevocationView 

Source
pub struct RevocationView { /* private fields */ }
Expand description

Arc-swap-backed read-only snapshot store. Cheap to clone (it is itself an Arc internally) so embedding kernels can hand a clone to every dispatch worker.

Implementations§

Source§

impl RevocationView

Source

pub fn new() -> Self

Create a new view holding the RevocationSnapshot::empty sentinel.

Source

pub fn load(&self) -> Arc<RevocationSnapshot>

Borrow the currently-installed snapshot for the lifetime of the returned guard. Readers never block writers and vice versa.

Source

pub fn install_if_newer( &self, candidate: RevocationSnapshot, ) -> Result<Arc<RevocationSnapshot>, RevocationViewError>

Replace the snapshot iff candidate.epoch > current.epoch.

Returns the previously-installed snapshot on success. Returns RevocationViewError::NonMonotoneEpoch when the candidate’s epoch does not strictly advance the current one; the active snapshot is left unchanged in that case (fail-closed).

Source

pub fn is_revoked(&self, subject: &RevocationViewSubject) -> bool

Convenience for the most common dispatch lookup.

Source

pub fn current_epoch(&self) -> u64

Currently-installed epoch counter. Cheap (no clone of the snapshot body).
