Enum RequestId 

pub enum RequestId {
    Num(u64),
    Str(String),
    Null,
}

Per-request correlation id.

JSON-RPC 2.0 permits numeric, string, or null ids; a server echoes the id unchanged. Null is reserved for notifications (DIG RPC does not use them but accepts the variant for spec compliance).

Variants

Num(u64)

Numeric id (the typical choice).

Str(String)

String id (useful for UUID correlation).

Null

Null id (spec-allowed for notifications).
