Struct io_uring::opcode::Readv

pub struct Readv { /* private fields */ }

Vectored read, equivalent to preadv2(2).

Implementations

impl Readv

pub fn new(fd: impl UseFixed, iovec: *const iovec, len: u32) -> Self

pub const CODE: u8 = 1u8

The opcode of the operation. This can be passed to Probe::is_supported to check if this operation is supported with the current kernel.

pub const fn ioprio(self, ioprio: u16) -> Self

pub const fn offset64(self, offset64: off64_t) -> Self

pub const fn rw_flags(self, rw_flags: RwFlags) -> Self

specified for read operations, contains a bitwise OR of per-I/O flags, as described in the preadv2(2) man page.

pub const fn buf_group(self, buf_group: u16) -> Self

pub fn build(self) -> Entry

impl Readv

pub const fn offset(self, offset: off_t) -> Self
