Struct WsResponse 

pub struct WsResponse {
    pub id: Uuid,
    pub result: Option<Value>,
    pub error: Option<String>,
}

A response from server to client, matching a request id.

Serde invariant

result: Some(Value::Null) and result: None are equivalent on the wire. Both serialize to a JSON object without a result field (the Some(Null) case via the standard serde rule that JSON null deserializes back as None for Option<T>). This is intentional and matches JSON-RPC convention. Pinned by a unit test below (ws_response_some_null_equals_none_on_wire).

If you need to distinguish “no result” from “result is JSON null” across the wire, change the field type to Option<Option<Value>> and use serde_with::rust::double_option. This is a deliberately non-default choice; do not make it without coordination.

Fields

id: Uuid

result: Option<Value>

error: Option<String>
