pub struct LocalKey<T: 'static> { /* private fields */ }Expand description
A thread local storage key which owns its contents
Implementations§
source§impl<T: 'static> LocalKey<T>
impl<T: 'static> LocalKey<T>
sourcepub fn with<F, R>(&'static self, f: F) -> R
pub fn with<F, R>(&'static self, f: F) -> R
Acquires a reference to the value in this TLS key.
This will lazily initialize the value if this thread has not referenced this key yet.
sourcepub fn try_with<F, R>(&'static self, f: F) -> Result<R, AccessError>
pub fn try_with<F, R>(&'static self, f: F) -> Result<R, AccessError>
Acquires a reference to the value in this TLS key.
This will lazily initialize the value if this thread has not referenced this key yet. If the key has been destroyed (which may happen if this is called in a destructor), this function will return an AccessError.
