Struct thrift::transport::TBufferedReadTransport

pub struct TBufferedReadTransport<C> where
    C: Read,  { /* fields omitted */ }

Transport that reads messages via an internal buffer.

A TBufferedReadTransport maintains a fixed-size internal read buffer. On a call to TBufferedReadTransport::read(...) one full message - both fixed-length header and bytes - is read from the wrapped channel and buffered. Subsequent read calls are serviced from the internal buffer until it is exhausted, at which point the next full message is read from the wrapped channel.

Examples

Create and use a TBufferedReadTransport.

use std::io::Read;
use thrift::transport::{TBufferedReadTransport, TTcpChannel};

let mut c = TTcpChannel::new();
c.open("localhost:9090").unwrap();

let mut t = TBufferedReadTransport::new(c);

t.read(&mut vec![0u8; 1]).unwrap();

Trait Implementations

impl<C: Debug> Debug for TBufferedReadTransport<C> where
    C: Read, 

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

Formats the value using the given formatter.

impl<C> Read for TBufferedReadTransport<C> where
    C: Read, 

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.

unsafe fn initializer(&self) -> Initializer

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

Determines if this Reader can work with buffers of uninitialized memory.

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, 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 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 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.
