{ /* private fields */ }

Fixed-size thread-pool blocking Thrift server.

A TServer listens on a given address and submits accepted connections to an unbounded queue. Connections from this queue are serviced by the first available worker thread from a fixed-size thread pool. Each accepted connection is handled by that worker thread, and communication over this thread occurs sequentially and synchronously (i.e. calls block). Accepted connections have an input half and an output half, each of which uses a TTransport and TInputProtocol/TOutputProtocol to translate messages to and from byes. Any combination of TInputProtocol, TOutputProtocol and TTransport may be used.

Examples

Creating and running a TServer using Thrift-compiler-generated service code.

use thrift::protocol::{TInputProtocolFactory, TOutputProtocolFactory};
use thrift::protocol::{TBinaryInputProtocolFactory, TBinaryOutputProtocolFactory};
use thrift::protocol::{TInputProtocol, TOutputProtocol};
use thrift::transport::{TBufferedReadTransportFactory, TBufferedWriteTransportFactory,
                        TReadTransportFactory, TWriteTransportFactory};
use thrift::server::{TProcessor, TServer};

//
// auto-generated
//

// processor for `SimpleService`
struct SimpleServiceSyncProcessor;
impl SimpleServiceSyncProcessor {
    fn new<H: SimpleServiceSyncHandler>(processor: H) -> SimpleServiceSyncProcessor {
        unimplemented!();
    }
}

// `TProcessor` implementation for `SimpleService`
impl TProcessor for SimpleServiceSyncProcessor {
    fn process(&self, i: &mut dyn TInputProtocol, o: &mut dyn TOutputProtocol) -> thrift::Result<()> {
        unimplemented!();
    }
}

// service functions for SimpleService
trait SimpleServiceSyncHandler {
    fn service_call(&self) -> thrift::Result<()>;
}

//
// user-code follows
//

// define a handler that will be invoked when `service_call` is received
struct SimpleServiceHandlerImpl;
impl SimpleServiceSyncHandler for SimpleServiceHandlerImpl {
    fn service_call(&self) -> thrift::Result<()> {
        unimplemented!();
    }
}

// instantiate the processor
let processor = SimpleServiceSyncProcessor::new(SimpleServiceHandlerImpl {});

// instantiate the server
let i_tr_fact: Box<dyn TReadTransportFactory> = Box::new(TBufferedReadTransportFactory::new());
let i_pr_fact: Box<dyn TInputProtocolFactory> = Box::new(TBinaryInputProtocolFactory::new());
let o_tr_fact: Box<dyn TWriteTransportFactory> = Box::new(TBufferedWriteTransportFactory::new());
let o_pr_fact: Box<dyn TOutputProtocolFactory> = Box::new(TBinaryOutputProtocolFactory::new());

let mut server = TServer::new(
    i_tr_fact,
    i_pr_fact,
    o_tr_fact,
    o_pr_fact,
    processor,
    10
);

// start listening for incoming connections
match server.listen("127.0.0.1:8080") {
  Ok(_)  => println!("listen completed"),
  Err(e) => println!("listen failed with error {:?}", e),
}

Implementations

impl<PRC, RTF, IPF, WTF, OPF> TServer<PRC, RTF, IPF, WTF, OPF>

where PRC: TProcessor + Send + Sync + 'static, RTF: TReadTransportFactory + 'static, IPF: TInputProtocolFactory + 'static, WTF: TWriteTransportFactory + 'static, OPF: TOutputProtocolFactory + 'static,

pub fn new( read_transport_factory: RTF, input_protocol_factory: IPF, write_transport_factory: WTF, output_protocol_factory: OPF, processor: PRC, num_workers: usize, ) -> TServer<PRC, RTF, IPF, WTF, OPF>

Create a TServer.

Each accepted connection has an input and output half, each of which requires a TTransport and TProtocol. TServer uses read_transport_factory and input_protocol_factory to create implementations for the input, and write_transport_factory and output_protocol_factory to create implementations for the output.

pub fn listen<A: ToSocketAddrs>(&mut self, listen_address: A) -> Result<()>

Listen for incoming connections on listen_address.

listen_address should implement ToSocketAddrs trait.

Return () if successful.

Return Err when the server cannot bind to listen_address or there is an unrecoverable error.

pub fn listen_uds<P: AsRef<Path>>(&mut self, listen_path: P) -> Result<()>

Listen for incoming connections on listen_path.

listen_path should implement AsRef<Path> trait.

Return () if successful.

Return Err when the server cannot bind to listen_path or there is an unrecoverable error.
