Struct mio_aio::LioCbBuilder

pub struct LioCbBuilder<'a>(_);

Used to construct LioCb.

LioCb uses the builder pattern. An LioCbBuilder is the only way to construct an LioCb.

LioCb

Implementations

impl<'a> LioCbBuilder<'a>

pub fn emplace_mut_slice(
    self,
    fd: RawFd,
    offset: u64,
    buf: &'a mut [u8],
    prio: i32,
    opcode: LioOpcode
) -> Self

Add a new operation on a mutable slice

Arguments

fd - File descriptor the file to read from or write to. offset - Offset within the file to read from or write to. buf - Memory location for the data prio - I/O priority. Not supported by all operating systems. opcode - Should be either LIO_READ or LIO_WRITE.

pub fn emplace_slice(
    self,
    fd: RawFd,
    offset: u64,
    buf: &'a [u8],
    prio: i32,
    opcode: LioOpcode
) -> Self

Add a new operation on an immutable mutable slice

Arguments

fd - File descriptor the file to read from or write to. offset - Offset within the file to read from or write to. buf - Memory location for the data prio - I/O priority. Not supported by all operating systems. opcode - Should be either LIO_READ or LIO_WRITE.

pub fn finish(self) -> LioCb<'a>

Complete the build into an LioCb, ready to use.

The operating system requires a stable memory location once I/O is submitted, so no new operations may be added after finish.

pub fn with_capacity(capacity: usize) -> LioCbBuilder<'a>

Create a new LioCbBuilder with room for capacity operations.

Formats the value using the given formatter.
