Struct Cache 

pub struct Cache { /* private fields */ }

In-memory caches for decoded transactions and resolved prevouts.

Shared across the graph builder and server via Arc<Cache>. Uses a concurrent quick cache implementation so lookups and inserts do not require an external async mutex. Entries are evicted automatically once the configured capacities are reached.

Implementations

impl Cache

pub fn new() -> Self

Create a cache with the default capacities

pub fn with_capacity(tx_cap: usize, prevout_cap: usize) -> Self

Create a cache with explicit capacities. Both values must be > 0.

pub async fn get_tx(&self, txid: &Txid) -> Option<TxNode>

Look up a cached transaction by txid.

pub async fn insert_tx(&self, txid: Txid, node: TxNode)

Insert a decoded transaction into the cache.

pub async fn get_prevout(&self, txid: &Txid, vout: u32) -> Option<TxOutput>

Look up cached prevout info for a specific outpoint.

pub async fn insert_prevout(&self, txid: Txid, vout: u32, info: TxOutput)

Cache resolved prevout data for a specific outpoint.

Trait Implementations

impl Default for Cache

fn default() -> Self

Returns the “default value” for a type.
