Struct Builder

pub struct Builder(/* private fields */);

IoUring build params

Implementations

impl Builder

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

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

Build a IoUring.
