Struct JsonRpcBatch 

pub struct JsonRpcBatch<T> {
    pub items: Vec<T>,
}

👎Deprecated since 2.2.3: JSON-RPC batching removed from MCP 2025-06-18 spec (PR #416). This type exists only for defensive handling and will be removed.

JSON-RPC batch request/response

IMPORTANT: JSON-RPC batching is NOT supported in MCP 2025-06-18 specification. This type exists only for defensive deserialization and will return errors if used. Per MCP spec changelog (PR #416), batch support was explicitly removed.

Do not use this type in new code. It will be removed in a future version.
