Struct flate2::gz::bufread::Buffer

struct Buffer<'a, T: 'a> {
    part: &'a mut GzHeaderPartial,
    buf_cur: usize,
    buf_max: usize,
    reader: &'a mut T,
}

A small adapter which reads data originally from buf and then reads all further data from reader. This will also buffer all data read from reader into buf for reuse on a further call.

Fields

part: &'a mut GzHeaderPartial

buf_cur: usize

buf_max: usize

reader: &'a mut T

Implementations

impl<'a, T> Buffer<'a, T>

fn new(part: &'a mut GzHeaderPartial, reader: &'a mut T) -> Buffer<'a, T>

    T: Read, 

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

Trait Implementations

impl<'a, T: Read> Read for Buffer<'a, T>

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

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

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> 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, appending them to buf.

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

Read the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (read_buf)

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

Creates an adapter which will chain this stream with another.

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

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