Struct Open

pub struct Open<T: 'static> { /* private fields */ }

Expand description

A reader’s hold on a Backed signal, from open. Deref gives the wrapped signal’s API; dropping the guard lets the producer notice the last reader has left.

Implementations§

impl<T> Open<T>

pub fn signal(&self) -> &'static T

The wrapped signal with the 'static lifetime Deref cannot lend, for APIs taking &'static self such as Leased::lease. It outlives the guard, so keeping it past the drop escapes the count.

Trait Implementations§

impl<T> Deref for Open<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> Drop for Open<T>

fn drop(&mut self)

Executes the destructor for this type. Read more

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. Read more
