Upgrade rust/crates/num-derive to 0.3.3 am: b858c52f1f am: 4dd1a71c2a am: 8f7a116898 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/num-derive/+/1480701 Change-Id: I03aaa57e9e738c0367bf8762ae06e9e4703bbf2a
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.
