Struct rustc_ap_rustc_data_structures::sharded::Sharded

pub struct Sharded<T> { /* fields omitted */ }

An array of cache-line aligned inner locked structures with convenience methods.

Implementations

impl<T> Sharded<T>

pub fn new(value: impl FnMut() -> T) -> Self

pub fn get_shard_by_value<K: Hash + ?Sized>(&self, val: &K) -> &Lock<T>

The shard is selected by hashing val with FxHasher.

pub fn get_shard_by_index(&self, i: usize) -> &Lock<T>

pub fn lock_shards(&self) -> Vec<LockGuard<'_, T>>

pub fn try_lock_shards(&self) -> Option<Vec<LockGuard<'_, T>>>

    K: Borrow<Q>,
    Q: Hash + Eq, 

pub fn intern<Q>(&self, value: Q, make: impl FnOnce(Q) -> K) -> K where
    K: Borrow<Q>,
    Q: Hash + Eq,

Trait Implementations

impl<T: Clone> Clone for Sharded<T>

fn clone(&self) -> Sharded<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Default> Default for Sharded<T>

fn default() -> Self

Returns the “default value” for a type.
