Struct StatusCache

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

Implementations

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

pub fn clear_slot_entries(&mut self, slot: Slot)

pub fn get_status<K: AsRef<[u8]>>( &self, key: K, transaction_blockhash: &Hash, ancestors: &Ancestors, ) -> Option<(Slot, T)>

Check if the key is in any of the forks in the ancestors set and with a certain blockhash.

pub fn get_status_any_blockhash<K: AsRef<[u8]>>( &self, key: K, ancestors: &Ancestors, ) -> Option<(Slot, T)>

Search for a key with any blockhash Prefer get_status for performance reasons, it doesn’t need to search all blockhashes.

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 keys are cleared.

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

pub fn insert<K: AsRef<[u8]>>( &mut self, transaction_blockhash: &Hash, key: K, slot: Slot, res: T, )

Insert a new key for a specific slot.

pub fn purge_roots(&mut self)

pub fn clear(&mut self)

Clear for testing

pub fn root_slot_deltas(&self) -> Vec<SlotDelta<T>>

Get the statuses for all the root slots

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> 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 for StatusCache<T>

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