Snap for 8564071 from 245b4fd71bfdeac91bb1da1881bc889a5b146da7 to mainline-sdkext-release Change-Id: I48d8246ba8ae456168c05241475714f4ed2a4e54
Procedural macros to derive numeric traits in Rust.
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, }
full-syntax
— Enables num-derive
to 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.Release notes are available in RELEASES.md.
The num-derive
crate is tested for rustc 1.31 and greater.
