Struct Readiness 

pub struct Readiness { /* private fields */ }

The consumer’s end: put it in a poll set, drain it, re-read your state.

Implementations

impl Readiness

pub fn drain(&self) -> Result<u64, Error>

Take every token the descriptor holds and return how many there were. Never blocks; a drained descriptor answers Ok(0).

The count is a local wake count. It says nothing about how many things changed in shared memory, which is what the consumer must re-read for itself.

fn as_raw_fd(&self) -> i32
