pub struct StatusCache<T: Serialize + Clone> { /* fields omitted */ }

Methods

impl<T: Serialize + Clone> StatusCache<T>

pub fn get_signature_status(
    &self,
    sig: &Signature,
    transaction_blockhash: &Hash,
    ancestors: &HashMap<Slot, usize>
) -> Option<(Slot, T)>

Check if the signature from a transaction is in any of the forks in the ancestors set.

pub fn get_signature_status_slow(
    &self,
    sig: &Signature,
    ancestors: &HashMap<Slot, usize>
) -> Option<SignatureConfirmationStatus<T>>

pub fn add_root(&mut self, fork: Slot)

Add a known root fork. Roots are always valid ancestors. After MAX_CACHE_ENTRIES, roots are removed, and any old signatures are cleared.

pub fn roots(&self) -> &HashSet<u64>

pub fn insert(
    &mut self,
    transaction_blockhash: &Hash,
    sig: &Signature,
    slot: Slot,
    res: T
)

Insert a new signature for a specific slot.

pub fn purge_roots(&mut self)

pub fn clear_signatures(&mut self)

Clear for testing

pub fn slot_deltas(&self, slots: &[Slot]) -> Vec<SlotDelta<T>>

pub fn append(&mut self, slot_deltas: &[SlotDelta<T>])

pub fn from_slot_deltas(slot_deltas: &[SlotDelta<T>]) -> Self

Trait Implementations

impl<T: Clone + Serialize> Clone for StatusCache<T>

fn clone(&self) -> StatusCache<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Serialize + Clone> Debug for StatusCache<T>

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

Formats the value using the given formatter.

impl<T: Serialize + Clone> Default for StatusCache<T>

fn default() -> Self

Returns the "default value" for a type.

impl<T: Serialize + Clone + PartialEq> PartialEq<StatusCache<T>> for StatusCache<T>

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