Enum JsonRpcMessage 

pub enum JsonRpcMessage<Req = Request, Resp = JsonObject, Noti = Notification> {
    Request(JsonRpcRequest<Req>),
    Response(JsonRpcResponse<Resp>),
    Notification(JsonRpcNotification<Noti>),
    Error(JsonRpcError),
}

Represents any JSON-RPC message that can be sent or received.

This enum covers all possible message types in the JSON-RPC protocol: individual requests/responses, notifications, and errors. It serves as the top-level message container for MCP communication.

Variants

Request(JsonRpcRequest<Req>)

A single request expecting a response

Response(JsonRpcResponse<Resp>)

A response to a previous request

Notification(JsonRpcNotification<Noti>)

A one-way notification (no response expected)

Error(JsonRpcError)

An error response

Trait Implementations

impl<Req: Clone, Resp: Clone, Noti: Clone> Clone for JsonRpcMessage<Req, Resp, Noti>

fn clone(&self) -> JsonRpcMessage<Req, Resp, Noti>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Req: Debug, Resp: Debug, Noti: Debug> Debug for JsonRpcMessage<Req, Resp, Noti>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, Req, Resp, Noti> Deserialize<'de> for JsonRpcMessage<Req, Resp, Noti>

where Req: Deserialize<'de>, Resp: Deserialize<'de>, Noti: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Req, Resp, Noti> JsonSchema for JsonRpcMessage<Req, Resp, Noti>

where Noti: JsonSchema, Req: JsonSchema, Resp: JsonSchema,

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl<Req: PartialEq, Resp: PartialEq, Noti: PartialEq> PartialEq for JsonRpcMessage<Req, Resp, Noti>

fn eq(&self, other: &JsonRpcMessage<Req, Resp, Noti>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<Req, Resp, Noti> Serialize for JsonRpcMessage<Req, Resp, Noti>

where Req: Serialize, Resp: Serialize, Noti: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
