Struct Splice 

pub struct Splice { /* private fields */ }

Zero-copy data transfer between two file descriptors.

Uses the kernel’s splice(2) syscall to move data directly from one file descriptor to another through the kernel pipe buffer. No data crosses the kernel-userspace boundary.

Requirements

At least one of fd_in or fd_out must be a pipe. For file-to-pipe transfers (the warpscan output path), open the source file and splice directly to stdout.

Example

use wireshift_core::ops::Splice;
use std::fs::File;

let src = File::open("data.bin").unwrap();
let dst = File::create("/dev/stdout").unwrap();
let op = Splice::new(src, Some(0), dst, None, 4096).unwrap();

Implementations

impl Splice

pub fn new( fd_in: File, off_in: Option<u64>, fd_out: File, off_out: Option<u64>, len: usize, ) -> Result<Self>

Create a new splice operation.

Errors

Returns an error if len is zero.

Trait Implementations

impl Op for Splice

type Output = SpliceResult

Successful output type.

fn name(&self) -> &'static str

Stable operation name for tracing and diagnostics.

fn into_descriptor(self) -> Result<OpDescriptor>

Converts the operation into a backend descriptor.

fn map_completion(payload: CompletionPayload) -> Result<Self::Output>

Maps a backend payload into the public output type.
