Struct io_uring::IoUring

pub struct IoUring { /* fields omitted */ }

IoUring instance

Implementations

impl IoUring

pub fn new(entries: u32) -> Result<IoUring>

Create a IoUring instance

The entries sets the size of queue, and it value should be the power of two.

pub fn submitter(&self) -> Submitter

pub fn params(&self) -> &Parameters

pub unsafe fn enter(
    &self,
    to_submit: u32,
    min_complete: u32,
    flag: u32,
    sig: Option<&sigset_t>
) -> Result<usize>

Initiate and/or complete asynchronous I/O

Safety

This provides a raw interface so developer must ensure that parameters are correct.

pub fn submit(&self) -> Result<usize>

Initiate asynchronous I/O.

pub fn submit_and_wait(&self, want: usize) -> Result<usize>

Initiate and/or complete asynchronous I/O

pub fn split(
    &mut self
) -> (Submitter, &mut SubmissionQueue, &mut CompletionQueue)

Get submitter and submission queue and completion queue

pub fn submission(&mut self) -> &mut SubmissionQueue

Get submission queue

pub fn completion(&mut self) -> &mut CompletionQueue

Get completion queue

pub fn concurrent(self) -> IoUring

Make a concurrent IoUring.
