Struct JsonRpcClient 

pub struct JsonRpcClient { /* private fields */ }

A JSON-RPC 2.0 client that communicates over line-delimited JSON on the stdin/stdout of a child process.

Implementations

impl JsonRpcClient

pub fn new(stdin: ChildStdin, stdout: ChildStdout) -> Self

Create a new client.

Spawns a background tokio task that reads line-delimited JSON from stdout, routing responses to their pending futures and everything else (notifications / incoming RPC calls) to an mpsc channel retrievable via [take_incoming].

pub fn take_incoming(&mut self) -> Option<UnboundedReceiver<IncomingMessage>>

Take the receiver for incoming notifications and RPC calls.

This can only be called once — subsequent calls return None.

pub async fn request( &self, method: &str, params: Option<Value>, ) -> Result<Response, Box<dyn Error + Send + Sync>>

Send a JSON-RPC request and wait for the matching response.

pub async fn notify( &self, method: &str, params: Option<Value>, ) -> Result<(), Box<dyn Error + Send + Sync>>

Send a JSON-RPC notification (no id, no response expected).

pub async fn respond( &self, id: u64, result: Option<Value>, error: Option<RpcError>, ) -> Result<(), Box<dyn Error + Send + Sync>>

Send a JSON-RPC response to an incoming RPC call from the agent.
