Struct FallbackState Copy item path

impl FallbackState

pub(crate) fn choose<R: Rng>( &self, rng: &mut R, now: Instant, filter: &GuardFilter, ) -> Result<&FallbackDir, PickGuardError>

Return a random member of this FallbackSet that’s usable at now.

fn next_retry(&self) -> Option<Instant>

Return the next time at which any member of this set will become ready.

Returns None if no elements are failing.

fn get(&self, id: &FallbackId) -> Option<&Entry>

Return a reference to the entry whose identity is id, if there is one.

fn get_mut(&mut self, id: &FallbackId) -> Option<&mut Entry>

Return a mutable reference to the entry whose identity is id, if there is one.

pub(crate) fn contains(&self, id: &FallbackId) -> bool

Return true if this set contains some entry with the given id.

pub(crate) fn note_success(&mut self, id: &FallbackId)

Record that a success has occurred for the fallback with the given identity.

Be aware that for fallbacks, we only count a successful directory operation as a success: a circuit success is not enough.

pub(crate) fn note_failure(&mut self, id: &FallbackId, now: Instant)

Record that a failure has occurred for the fallback with the given identity.

pub(crate) fn take_status_from(&mut self, other: FallbackState)

Consume other and copy all of its fallback status entries into the corresponding entries for self.

pub(crate) fn note_skew( &mut self, id: &FallbackId, observation: SkewObservation, )

Record that a given fallback has told us about clock skew.

pub(crate) fn skew_observations(&self) -> impl Iterator<Item = &SkewObservation>

Return an iterator over all the clock skew observations we’ve made for fallback directories
