Struct thrift::transport::TBufferedReadTransport

source ·
pub struct TBufferedReadTransport<C>
where C: Read,
{ /* private fields */ }
Expand description

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();
