Struct BufferReaderChild 

pub struct BufferReaderChild<'a, 'b> { /* private fields */ }

It acts like a copy of a parent BufferReader.

You can create this from BufferReader::child. The child offset will be set to 0, but its underlying buffer will start from the current parent’s offset.

Having a copy it allows reading the buffer preserving the parent’s original offset.

If you want to commit the number of bytes read to the parent, use BufferReaderChild::commit. Instead, dropping this without committing, it will not alter the parent.

Implementations

impl<'a, 'b> BufferReaderChild<'a, 'b>

pub fn commit(self)

Advances the parent BufferReader offset of the amount read with this child.

Methods from Deref<Target = BufferReader<'a>>

pub fn capacity(&self) -> usize

Returns the remaining capacity in the buffer.

pub fn offset(&self) -> usize

Returns the current offset of the buffer.

pub fn skip(&mut self, len: usize) -> Result<(), EndOfBuffer>

Advances the offset.

In case of Err the offset is not advanced.

pub fn buffer(&self) -> &'a [u8]

Returns a reference to the internal buffer.

Note: this is the entire buffer (despite offset).

pub fn buffer_remaining(&mut self) -> &'a [u8]

Returns the inner buffer starting from the current offset.

pub fn child(&mut self) -> BufferReaderChild<'a, '_>

Creates a BufferReaderChild with this parent.

Trait Implementations

impl<'a> Deref for BufferReaderChild<'a, '_>

type Target = BufferReader<'a>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for BufferReaderChild<'_, '_>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
