pub struct CachedThreadLocal<T: Send> { /* private fields */ }
👎 Deprecated since 1.1.0:

Use ThreadLocal instead

Expand description

Wrapper around ThreadLocal.

This used to add a fast path for a single thread, however that has been obsoleted by performance improvements to ThreadLocal itself.

Implementations

Creates a new empty CachedThreadLocal.

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

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

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.

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.

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.

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