Trait netstack3_base::Payload

pub trait Payload: PayloadLen + Sized {
    // Required methods
    fn slice(self, range: Range<u32>) -> Self;
    fn partial_copy(&self, offset: usize, dst: &mut [u8]);
    fn partial_copy_uninit(&self, offset: usize, dst: &mut [MaybeUninit<u8>]);
    fn new_empty() -> Self;
}

A TCP payload that operates around u32 instead of usize.

Required Methods

fn slice(self, range: Range<u32>) -> Self

Creates a slice of the payload, reducing it to only the bytes within range.

Panics

Panics if the provided range is not within the bounds of this Payload, or if the range is nonsensical (the end precedes the start).

fn partial_copy(&self, offset: usize, dst: &mut [u8])

Copies part of the payload beginning at offset into dst.

Panics

Panics if offset is too large or we couldn’t fill the dst slice.

fn partial_copy_uninit(&self, offset: usize, dst: &mut [MaybeUninit<u8>])

Copies part of the payload beginning at offset into dst.

Panics

Panics if offset is too large or we couldn’t fill the dst slice.

fn new_empty() -> Self

Creates a new empty payload.

An empty payload must report 0 as its length.

Object Safety

This trait is not object safe.
