Struct io_uring::opcode::Writev

source · [−]

pub struct Writev { /* private fields */ }

Expand description

Vectored write, equivalent to pwritev2(2).

Implementations

source

impl Writev

source

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

source

pub const CODE: u8 = 2u8

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

source

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

source

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

source

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

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

source

pub fn build(self) -> Entry
