Update TEST_MAPPING am: 6c385e4be0 am: ef50892bf4 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/num-derive/+/2108558 Change-Id: I305c051880defbe695aa9544311dadc16ef70c78 Signed-off-by: Automerger Merge Worker <[email protected]>
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.
