[LSC] Add LOCAL_LICENSE_KINDS to external/rust/crates/num-derive am: b1a5dea523 am: f0b67f40fd am: 0f4cc4d38d Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/num-derive/+/1587383 MUST ONLY BE SUBMITTED BY AUTOMERGER Change-Id: I3ca55cb75040a0215a4eb3dd913bfbefb5c390fb
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.
