Struct ReadBufCursor

pub struct ReadBufCursor<'a> { /* private fields */ }

The cursor part of a ReadBuf.

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

Implementations

impl<'data> ReadBufCursor<'data>

pub unsafe fn as_mut(&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.

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

Advance the filled cursor by n bytes.

Safety

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

pub fn remaining(&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()``.

pub fn put_slice(&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.

Trait Implementations

impl<'a> Debug for ReadBufCursor<'a>

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
