Struct thrift::protocol::TMultiplexedOutputProtocol

source ·
pub struct TMultiplexedOutputProtocol<P>
where P: TOutputProtocol,
{ /* private fields */ }
Expand description

TOutputProtocol that prefixes the service name to all outgoing Thrift messages.

A TMultiplexedOutputProtocol should be used when multiple Thrift services send messages over a single I/O channel. By prefixing service identifiers to outgoing messages receivers are able to demux them and route them to the appropriate service processor. Rust receivers must use a TMultiplexedProcessor to process incoming messages, while other languages must use their corresponding multiplexed processor implementations.

For example, given a service TestService and a service call test_call, this implementation would identify messages as originating from TestService:test_call.

§Examples

Create and use a TMultiplexedOutputProtocol.

use thrift::protocol::{TMessageIdentifier, TMessageType, TOutputProtocol};
use thrift::protocol::{TBinaryOutputProtocol, TMultiplexedOutputProtocol};
use thrift::transport::TTcpChannel;

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

let protocol = TBinaryOutputProtocol::new(channel, true);
let mut protocol = TMultiplexedOutputProtocol::new("service_name", protocol);

let ident = TMessageIdentifier::new("svc_call", TMessageType::Call, 1);
protocol.write_message_begin(&ident).unwrap();

Implementations§

source§

impl<P> TMultiplexedOutputProtocol<P>
where P: TOutputProtocol,

source

pub fn new(service_name: &str, wrapped: P) -> TMultiplexedOutputProtocol<P>

Create a TMultiplexedOutputProtocol that identifies outgoing messages as originating from a service named service_name and sends them over the wrapped TOutputProtocol. Outgoing messages are encoded and sent by wrapped, not by this instance.
