Low-level ABCI protocol server
This crate provides low-level access to the ABCI protocol, via a Connection type which exposes read() and write() methods which return or accept ABCI request or response structs.
Currently supports Tendermint 0.32.
Add this crate as a dependency:
[dependencies]
abci2 = "0.1"
Example: ```rust // listen for ABCI connections from Tendermint let server = abci2::Server::listen("localhost:26658").unwrap();
// wait for Tendermint to connect (note that we will need to accept the 3 // separate connections that Tendermint makes). this function blocks until // a connection comes in. let connection = server.accept().unwrap();
loop { // get an incoming request let req = connection.read().unwrap();
// handle the request somehow
let res = process_request();
// send back the response
connection.write(res).unwrap();
} ```
For a more complete example, see examples/simple.rs (you can run it via cargo run --example simple).
If you are updating this crate to protobuf definitions for a newer version of Tendermint, you can regenerate the code by running: cargo run --bin codegen --features codegen.
