Struct LockToken 

pub struct LockToken<'a, Class> { /* private fields */ }

A token proving that a lock of lock class Class is currently held by the current thread.

This token acts as a static proof to permit type-safe borrow access to cell values guarded by this lock class (via KCell).

Implementations

impl<'a, Class> LockToken<'a, Class>

pub unsafe fn new() -> Self

Creates a new proof token for the lock class Class.

Safety

The caller must guarantee that the mutual exclusion lock associated with this lock class is currently held by the current thread and that the lifetime 'a is bounded to the duration of the lock being held. Creating a token when the lock is not held, or letting the token outlive the lock hold duration, can lead to concurrent mutation or data races, which is undefined behavior.
