Struct netio::buf_redux_reexport::Unbuffer

pub struct Unbuffer<R> {
    // some fields omitted
}

A Read adapter for a consumed BufReader which will empty bytes from the buffer before reading from inner directly. Frees the buffer when it has been emptied.

Methods

impl<R> Unbuffer<R>

fn is_buf_empty(&self) -> bool

Returns true if the buffer still has some bytes left, false otherwise.

fn buf_len(&self) -> usize

Returns the number of bytes remaining in the buffer.

fn into_inner(self) -> R

Return the underlying reader, finally letting the buffer die in peace and join its family in allocation-heaven.

Trait Implementations

impl<R> Read for Unbuffer<R> where R: Read

fn read(&mut self, buf: &mut [u8]) -> Result<usize, Error>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

Unstable (io)

: the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

fn chain<R>(self, next: R) -> Chain<Self, R> where R: Read

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl<R> Debug for Unbuffer<R> where R: Debug

fn fmt(&self, fmt: &mut Formatter) -> Result<(), Error>
