pub struct Builder { /* fields omitted */ }

IoUring build params

Methods

impl Builder

pub fn dontfork(&mut self) -> &mut Self

pub fn feature_single_mmap(&mut self) -> &mut Self

Deprecated since 0.3.1:

unnecessary

pub fn setup_iopoll(&mut self) -> &mut Self

Perform busy-waiting for an I/O completion, as opposed to getting notifications via an asynchronous IRQ (Interrupt Request).

pub fn setup_sqpoll(&mut self, idle: impl Into<Option<u32>>) -> &mut Self

When this flag is specified, a kernel thread is created to perform submission queue polling. An io_uring instance configured in this way enables an application to issue I/O without ever context switching into the kernel.

pub fn setup_sqpoll_cpu(&mut self, n: u32) -> &mut Self

If this flag is specified, then the poll thread will be bound to the cpu set in the value. This flag is only meaningful when Builder::setup_sqpoll is enabled.

pub fn setup_cqsize(&mut self, n: u32) -> &mut Self

Create the completion queue with struct io_uring_params.cq_entries entries. The value must be greater than entries, and may be rounded up to the next power-of-two.

pub fn setup_clamp(&mut self) -> &mut Self

pub fn setup_attach_wq(&mut self, fd: RawFd) -> &mut Self

pub fn build(&self, entries: u32) -> Result<IoUring>

Build a IoUring.
