Struct WriteOp 

pub struct WriteOp {
    pub file: VfFile,
    pub offset: VfOffset,
    pub data: Vec<u8>,
    pub creation: bool,
    pub truncate: bool,
}

One element of a batched write.

Fields

file: VfFile

offset: VfOffset

data: Vec<u8>

creation: bool

Create the file if it does not exist.

truncate: bool

Truncate the file to zero before writing (POSIX O_TRUNC semantics fused into the same round trip as the write).

Implementations

impl WriteOp

pub fn new(file: VfFile, offset: VfOffset, data: Vec<u8>) -> WriteOp

pub fn at(file: VfFile, offset: u64, data: Vec<u8>) -> WriteOp

A write at an absolute offset.

pub fn from_path(path: &str, offset: VfOffset, data: Vec<u8>) -> WriteOp

pub fn from_os_path(path: &Path, offset: VfOffset, data: Vec<u8>) -> WriteOp

Construct a write from a native path.

pub fn from_fd(fd: i32, offset: VfOffset, data: Vec<u8>) -> WriteOp

pub fn with_creation(self) -> WriteOp

Create the file if it does not exist.

pub fn with_truncate(self) -> WriteOp

Truncate the file to zero before writing, in the same round trip.
