Implementations

impl<T> LazyKeyInner<T>

pub const fn new() -> LazyKeyInner<T>

🔬This is a nightly-only experimental API. (thread_local_internals)

pub unsafe fn get(&self) -> Option<&'static T>

🔬This is a nightly-only experimental API. (thread_local_internals)

pub unsafe fn initialize<F: FnOnce() -> T>(&self, init: F) -> &'static T

🔬This is a nightly-only experimental API. (thread_local_internals)

The caller must ensure that no reference is active: this method needs unique access.

pub unsafe fn take(&mut self) -> Option<T>

🔬This is a nightly-only experimental API. (thread_local_internals)

The other methods hand out references while taking &self. As such, callers of this method must ensure no & and &mut are available and used at the same time.
