Enum OperationType 

#[repr(u8)]
pub enum OperationType {
    Read = 0,
    Write = 1,
    Accept = 2,
    Send = 3,
    Recv = 4,
    ReadVectored = 5,
    WriteVectored = 6,
}

Type of I/O operation to perform.

This enum represents the different types of operations that can be submitted to io_uring. Each variant corresponds to a specific system call or operation type.

Variants

Read = 0

Read data from a file descriptor into a buffer

Write = 1

Write data from a buffer to a file descriptor

Accept = 2

Accept a connection on a listening socket

Send = 3

Send data on a socket

Recv = 4

Receive data from a socket

ReadVectored = 5

Vectored read operation (readv)

WriteVectored = 6

Vectored write operation (writev)

Implementations

impl OperationType

pub const fn requires_buffer(self) -> bool

Returns true if this operation type requires a buffer.

Accept operations don’t require a buffer as they only return a new file descriptor for the accepted connection.

pub const fn is_read_like(self) -> bool

Returns true if this operation type is a read-like operation.

Read-like operations populate the buffer with data from the kernel.

pub const fn is_write_like(self) -> bool

Returns true if this operation type is a write-like operation.

Write-like operations send data from the buffer to the kernel.

pub const fn is_vectored(self) -> bool

Returns true if this operation type is vectored.

Vectored operations use multiple buffers (scatter-gather I/O).

Trait Implementations

impl Clone for OperationType

fn clone(&self) -> OperationType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OperationType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for OperationType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for OperationType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OperationType

fn eq(&self, other: &OperationType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
