Example
Cargo.toml
[dependencies]
jsonrpc-core = "4.0"
main.rs
extern crate jsonrpc_core;
use jsonrpc_core::*;
struct SayHello;
impl SyncMethodCommand for SayHello {
fn execute(&self, _params: Params) -> Result<Value, Error> {
Ok(Value::String("hello".into()))
}
}
fn main() {
let io = IoHandler::new();
io.add_method("say_hello", SayHello);
let request = r#"{"jsonrpc": "2.0", "method": "say_hello", "params": [42, 23], "id": 1}"#;
let response = r#"{"jsonrpc":"2.0","result":"hello","id":1}"#;
assert_eq!(io.handle_request_sync(request), Some(response.to_owned()));
}
Asynchronous responses
main.rs
extern crate jsonrpc_core;
use jsonrpc_core::*;
struct SayHello;
impl MethodCommand for SayHello {
fn execute(&self, _params: Params, ready: Ready) {
ready.ready(Ok(Value::String("hello".into())))
}
}
fn main() {
let io = IoHandler::new();
io.add_async_method("say_hello", SayHello);
let request = r#"{"jsonrpc": "2.0", "method": "say_hello", "params": [42, 23], "id": 1}"#;
let response = r#"{"jsonrpc":"2.0","result":"hello","id":1}"#;
io.handle_request(request, move |res| {
assert_eq!(res, Some(response.to_owned()));
});
