Struct sp_trie :: cache :: SharedTrieCache Copy item path

impl<H: Hasher> SharedTrieCache<H>

pub fn new(cache_size: CacheSize) -> Self

Create a new SharedTrieCache.

pub fn local_cache(&self) -> LocalTrieCache<H>

Create a new LocalTrieCache instance from this shared cache.

pub fn peek_node(&self, key: &H::Out) -> Option<NodeOwned<H::Out>>

Get a copy of the node for key.

This will temporarily lock the shared cache for reading.

This doesn’t change the least recently order in the internal LruMap.

This will temporarily lock the shared cache for reading.

This doesn’t reorder any of the elements in the internal LruMap.

pub fn used_memory_size(&self) -> usize

Returns the used memory size of this cache in bytes.

pub fn reset_node_cache(&self)

Reset the node cache.

pub fn reset_value_cache(&self)
