Struct IoLifecycle 

pub struct IoLifecycle { /* private fields */ }

One revocable I/O generation shared by native execution contexts.

Acquisition and close update one atomic closed-bit/count word, so an operation is either counted before close or rejected after close. Cloning this handle does not itself count as active I/O.

Implementations

impl IoLifecycle

pub fn new() -> Self

pub fn acquire(&self, operation: &'static str) -> Result<IoLifecycleLease>

pub fn close(&self)

Close this generation without blocking. Repeated close calls are safe.

pub fn close_and_wait_for_idle_until( &self, deadline: Instant, operation: &'static str, ) -> Result<()>

Close and wait until every lease acquired before close has dropped.
