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();

Methods

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

fn new(channel: C) -> TBufferedReadTransport<C>

Create a TBufferedTransport with default-sized internal read and write buffers that wraps the given TIoChannel.

fn with_capacity(read_capacity: usize, channel: C) -> TBufferedReadTransport<C>

Create a TBufferedTransport with an internal read buffer of size read_capacity and an internal write buffer of size write_capacity that wraps the given TIoChannel.

Trait Implementations

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

fn fmt(&self, __arg_0: &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_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>

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