caret

caret: Integers with some named values.

Crikey! Another Rust Enum Tool?

Suppose you have an integer type with some named values. For example, you might be implementing a protocol where "command" can be any 8-bit value, but where only a small number of commands are recognized.

In that case, you can use the [caret_int] macro to define a wrapper around u8 so named values are displayed with their preferred format, but you can still represent all the other values of the field:

```rust use caret::caretint; caretint!{ struct Command(u8) { Get = 0, Put = 1, Swap = 2, } }

let c1: Command = 2.into(); let c2: Command = 100.into();

asserteq!(c1.tostring().asstr(), "Swap"); asserteq!(c2.tostring().asstr(), "100");

assert_eq!(c1, Command::Swap); ```

This crate is developed as part of Arti, a project to implement Tor in Rust. Many other crates in Arti depend on it, but it should be of general use.
