Merge "Refresh Android.bp, cargo2android.json, TEST_MAPPING." am: d3da86843f am: a328bdd699 am: e198a8e5b4 am: b91aab0674 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/num-derive/+/1912647 Change-Id: I3397371e0fe5d6883a00fe4b442ee1b7c8b7d152
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.
