Struct ReadBufCursor

struct ReadBufCursor<'a> { ... }

The cursor part of a ReadBuf.

This is created by calling ReadBuf::unfilled().

Implementations

impl ReadBufCursor<'_>

unsafe fn as_mut(self: &mut Self) -> &mut [MaybeUninit<u8>]

Access the unfilled part of the buffer.

Safety

The caller must not uninitialize any bytes that may have been initialized before.

unsafe fn advance(self: &mut Self, n: usize)

Advance the filled cursor by n bytes.

Safety

The caller must take care that n more bytes have been initialized.

fn remaining(self: &Self) -> usize

Returns the number of bytes that can be written from the current position until the end of the buffer is reached.

This value is equal to the length of the slice returned by `as_mut()``.

fn put_slice(self: &mut Self, src: &[u8])

Transfer bytes into self`` from src` and advance the cursor by the number of bytes written.

Panics

self must have enough remaining capacity to contain all of src.
