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();
