    buf: Box<[MaybeUninit<u8>]>,
    pos: usize,
    filled: usize,

}

initialized: usize

Implementations

impl Buffer

pub fn with_capacity(capacity: usize) -> Self

pub fn try_with_capacity(capacity: usize) -> Result<Self>

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

pub fn capacity(&self) -> usize

pub fn filled(&self) -> usize

pub fn pos(&self) -> usize

pub fn discard_buffer(&mut self)

pub fn consume(&mut self, amt: usize)

pub fn consume_with<V>(&mut self, amt: usize, visitor: V) -> bool

where V: FnMut(&[u8]),

If there are amt bytes available in the buffer, pass a slice containing those bytes to visitor and return true. If there are not enough bytes available, return false.

pub fn unconsume(&mut self, amt: usize)

pub fn read_more(&mut self, reader: impl Read) -> Result<usize>

Read more bytes into the buffer without discarding any of its contents

pub fn backshift(&mut self)

Remove bytes that have already been read from the buffer.

pub fn fill_buf(&mut self, reader: impl Read) -> Result<&[u8]>
