Struct PrecompileCache 

pub struct PrecompileCache { /* private fields */ }

Per-block cache for precompile results shared between warmer and executor.

Holds at most PRECOMPILE_CACHE_MAX_BYTES, as counted by PrecompileCache::entry_size; once full, further results are simply not cached. Nothing is evicted: the cache is dropped with its block, so there is no recency worth tracking, and lookups stay on the shared read lock.

Implementations

impl PrecompileCache

pub fn new() -> Self

pub fn entry_size(calldata_len: usize, output_len: usize) -> usize

Bytes one entry is charged against the budget: its calldata and output, plus the fixed size of the key and value it is stored as. Hash-table slack is not counted, so the budget is approximate, not an exact resident size.

pub fn get(&self, address: &Address, calldata: &Bytes) -> Option<(Bytes, u64)>

pub fn insert( &self, address: Address, calldata: Bytes, output: Bytes, gas_cost: u64, )

Trait Implementations

impl Default for PrecompileCache

fn default() -> Self

Returns the “default value” for a type.
