# Description In this PR I replaced most of the raw usize IDs with [newtypes](https://doc.rust-lang.org/rust-by-example/generics/new_types.html). Some other IDs already started using new types and in this PR I did not want to touch them. To make the implementation less repetitive, I made use of a generic `Id<T>` with marker structs. If this lands I would try to move make other IDs also in this pattern. Also at some places I needed to use `cast`, I'm not sure if the type was incorrect and therefore casting not needed or if actually different ID types intermingle sometimes. # User-Facing Changes Probably few, if you got a `DeclId` via a function and placed it later again it will still work. |

nu-protocol
The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
