}Expand description

sourcefn write_count(&self, v: u64) -> Result<()>
fn write_count(&self, v: u64) -> Result<()>
Adds v to the eventfd’s count, blocking until this won’t overflow the count.
sourcefn read_count(&self) -> Result<u64>
fn read_count(&self) -> Result<u64>
Blocks until the the eventfd’s count is non-zero, then resets the count to zero.
