Struct ReadLock 

pub struct ReadLock { /* private fields */ }

Read claim held without a reference to the value.

Useful for keeping a value readable across code that does not touch it. Releases the claim on drop.

Implementations

impl ReadLock

pub unsafe fn new_raw(lifetime: LifetimeState) -> Self

Builds a lock from a state, without going through the state checks.

Safety

The read claim on lifetime must already be acquired, since dropping this lock releases one.

pub fn using<R>(self, f: impl FnOnce() -> R) -> R

Runs f while holding the lock, then releases it.

Trait Implementations

impl Drop for ReadLock

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
