Struct Response 

pub struct Response {
    pub jsonrpc: String,
    pub id: RequestId,
    pub result: Option<Value>,
    pub error: Option<ResponseError>,
}

One JSON-RPC response. Either result or error is set; never both.

Decoding does not enforce the “never both” half: a message carrying both decodes with both set, and consumers check error first. A message with an id but neither key is not a response at all — Message::from_json rejects it as MessageDecodeError::Malformed.

A successful result of JSON null (e.g. shutdown’s) deserializes to result: None, indistinguishable from an absent key.

Fields

jsonrpc: String

Protocol version; JSONRPC_VERSION on everything we build.

id: RequestId

The id of the Request this answers, echoed unchanged.

result: Option<Value>

The success payload.

error: Option<ResponseError>

The failure payload.

Implementations
