Struct thread_local::ThreadLocal
[−]
[src]
pub struct ThreadLocal<T: ?Sized + Send> { /* fields omitted */ }
Thread-local variable wrapper
See the module-level documentation for more.
Methods
impl<T: ?Sized + Send> ThreadLocal<T>[src]
fn new() -> ThreadLocal<T>[src]
Creates a new empty ThreadLocal.
fn get(&self) -> Option<&T>[src]
Returns the element for the current thread, if it exists.
fn get_or<F>(&self, create: F) -> &T where
F: FnOnce() -> Box<T>, [src]
F: FnOnce() -> Box<T>,
Returns the element for the current thread, or creates it if it doesn't exist.
fn get_or_try<F, E>(&self, create: F) -> Result<&T, E> where
F: FnOnce() -> Result<Box<T>, E>, [src]
F: FnOnce() -> Result<Box<T>, E>,
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.
fn iter_mut(&mut self) -> IterMut<T>[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.
fn clear(&mut self)[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> ThreadLocal<T>[src]
fn get_default(&self) -> &T[src]
Returns the element for the current thread, or creates a default one if it doesn't exist.
