Struct thread_local::CachedThreadLocal [] [src]

pub struct CachedThreadLocal<T: ?Sized + Send> { /* fields omitted */ }

Wrapper around ThreadLocal which adds a fast path for a single thread.

This has the same API as ThreadLocal, but will register the first thread that sets a value as its owner. All accesses by the owner will go through a special fast path which is much faster than the normal ThreadLocal path.

Methods

impl<T: ?Sized + Send> CachedThreadLocal<T>
[src]

[src]

Creates a new empty CachedThreadLocal.

[src]

Returns the element for the current thread, if it exists.

[src]

Returns the element for the current thread, or creates it if it doesn't exist.

[src]

Returns the element for the current thread, or creates it if it doesn't exist. If create fails, that error is returned and no element is added.

[src]

Returns a mutable iterator over the local values of all threads.

Since this call borrows the ThreadLocal mutably, this operation can be done safely---the mutable borrow statically guarantees no other threads are currently accessing their associated values.

[src]

Removes all thread-specific values from the ThreadLocal, effectively reseting it to its original state.

Since this call borrows the ThreadLocal mutably, this operation can be done safely---the mutable borrow statically guarantees no other threads are currently accessing their associated values.

impl<T: Send + Default> CachedThreadLocal<T>
[src]

[src]

Returns the element for the current thread, or creates a default one if it doesn't exist.
