Struct Message 

#[non_exhaustive]
pub struct Message {
    pub jsonrpc: String,
    pub id: Option<RequestId>,
    pub method: Option<String>,
    pub params: Option<Value>,
    pub result: Option<Value>,
    pub error: Option<JsonRpcError>,
}

An incoming JSON-RPC message.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

jsonrpc: String

Always "2.0".

id: Option<RequestId>

Optional ID — present for requests and responses, absent for notifications.

method: Option<String>

Method name — present for requests and notifications, absent for responses.

params: Option<Value>

Parameters — present for requests and notifications.

result: Option<Value>

Result — present for successful responses.

error: Option<JsonRpcError>

Error — present for failed responses.

Implementations
