Struct ReadOp 

pub struct ReadOp {
    pub file: FileOperand,
    pub offset: VfOffset,
    pub length: usize,
}

One element of a batched read, replacing the C tc_iovec (which mixed input and output fields in a single mutable struct).

Fields

file: FileOperand

offset: VfOffset

length: usize

Number of bytes to fetch.

Implementations

impl ReadOp

pub fn new(file: FileOperand, offset: VfOffset, length: usize) -> ReadOp

pub fn at(file: FileOperand, offset: u64, length: usize) -> ReadOp

A read at an absolute offset.

pub fn from_path(path: &str, offset: VfOffset, length: usize) -> ReadOp

pub fn from_os_path(path: &Path, offset: VfOffset, length: usize) -> ReadOp

Construct a read from a native path.

pub fn from_fd(fd: i32, offset: VfOffset, length: usize) -> ReadOp

A read from an open descriptor, typically at VfOffset::Cur (sequential) reads.

Trait Implementations

impl Clone for ReadOp

fn clone(&self) -> ReadOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadOp

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

Formats the value using the given formatter.
