num-derive
Procedural macros to derive numeric traits in Rust.
Usage
Add this to your Cargo.toml:
[dependencies]
num-traits = "0.2"
num-derive = "0.3"
and this to your crate root:
#[macro_use]
extern crate num_derive;
Then you can derive traits on your own types:
#[derive(FromPrimitive, ToPrimitive)]
enum Color {
Red,
Blue,
Green,
}
Optional features
full-syntax— Enablesnum-deriveto handle enum discriminants represented by complex expressions. Usually can be avoided by utilizing constants, so only use this feature if namespace pollution is undesired and compile time doubling is acceptable.
Releases
Release notes are available in RELEASES.md.
Compatibility
The num-derive crate is tested for rustc 1.31 and greater.
