Struct ConcurrentHashTable 

pub struct ConcurrentHashTable<V, const N: usize> { /* private fields */ }

A hash table that shards to a constant number of tables to reduce lock contention

Implementations

impl<V, const N: usize> ConcurrentHashTable<V, N>

where [RwLock<HashMap<u128, V>>; N]: Default,

pub fn new() -> Self

pub fn get(&self, key: u128) -> &RwLock<HashMap<u128, V>>

pub fn get_shard_at_idx(&self, idx: usize) -> Option<&RwLock<HashMap<u128, V>>>

pub fn read(&self, key: u128) -> RwLockReadGuard<'_, HashMap<u128, V>>

pub fn write(&self, key: u128) -> RwLockWriteGuard<'_, HashMap<u128, V>>

pub fn for_each<F>(&self, f: F)

where F: FnMut(&u128, &V),
