3/// A identifier for tracking [`Request`s](super::Request) and [`Response`s](super::Response).
4/// An identifier can be a String or Number if included.
5///
6/// The [JSON-RPC spec]() defines the number as ["containing no fractional
7/// parts"](https://www.jsonrpc.org/specification#id2), and LSP defines Numbers as integers
8/// ["in the range of -2^31 to 2^31 - 1"](https://microsoft.github.io/language-server-protocol/specifications/specification-3-16/#integer)
9/// (so they're [`i32`] in Rust parlance).
10///
11/// Strings have no constraints on them, but for example could be a UUID.
