Struct solana_runtime::status_cache::StatusCache

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<ForkId, usize>
) -> Option<(ForkId, 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<ForkId, usize>
) -> Option<(usize, T)>

TODO: wallets should send the Transactions recent blockhash as well

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

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 insert(
    &mut self,
    transaction_blockhash: &Hash,
    sig: &Signature,
    fork: ForkId,
    res: T
)

Insert a new signature for a specific fork.

pub fn clear_signatures(&mut self)

Clear for testing

pub fn append(&mut self, status_cache: &StatusCache<T>)

pub fn merge_caches(&mut self)

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

fn default() -> Self

Returns the "default value" for a type.

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)

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

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

Serialize this value into the given Serde serializer.
