[−][src]Struct io_uring::opcode::WriteFixed

pub struct WriteFixed { /* fields omitted */ }

Write to pre-mapped buffers that have been previously registered with Submitter::register_buffers.

The return values match those documented in the pwritev2(2) man pages.

Implementations

impl WriteFixed[src]

pub fn new(fd: impl UseFixed, buf: *const u8, len: u32, buf_index: u16) -> Self[src]

The buf_index is an index into an array of fixed buffers, and is only valid if fixed buffers were registered.

pub const CODE: u8[src]

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[src]

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

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

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

pub fn build(self) -> Entry[src]
