Struct WriterPumpGuard 

pub struct WriterPumpGuard { /* private fields */ }

The spawned writer pump and the only strong frame sender, retired together on every exit path.

The sender lives here rather than beside the guard because the pump parks on rx.recv() and leaves only when the last strong sender drops. A guard that joined without dropping the sender would hang; keeping the two in one value means the order cannot be got wrong, and does not depend on the declaration order of two separate locals.

Trait Implementations

impl Drop for WriterPumpGuard

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.
