# Compatibility
|
|
|
|
|
|
2021-06-02 03:32:56 +02:00
|
|
|
Strum is currently with versions of rustc >= 1.32.0. Pull Requests that improve compatibility with older
|
|
|
|
|
versions are welcome. The project goal is to support a rust version for at least 2 years after release
|
|
|
|
|
and even longer is preferred since this project changes slowly.

# Including Strum in Your Project
|
|
|
|
|
|
|
|
|
|
Import strum and strum_macros into your project by adding the following lines to your
|
|
|
|
|
Cargo.toml. Strum_macros contains the macros needed to derive all the traits in Strum.
|
|
|
|
|
|
|
|
|
|
```toml
|
|
|
|
|
[dependencies]
|
2021-11-17 07:24:17 +01:00
|
|
|
strum = "0.23"
|
|
|
|
|
strum_macros = "0.23"
|
2020-10-07 07:52:12 +02:00
|
|
|
|
|
|
|
|
# You can also use the "derive" feature, and import the macros directly from "strum"
|
2021-11-17 07:24:17 +01:00
|
|
|
# strum = { version = "0.23", features = ["derive"] }

Thanks for your interest in contributing. The project is divided into 3 parts, the traits are in the
|
|
|
|
|
`/strum` folder. The procedural macros are in the `/strum_macros` folder, and the integration tests are
|
|
|
|
|
in `/strum_tests`. If you are adding additional features to `strum` or `strum_macros`, you should make sure
|
2017-02-23 09:09:57 +01:00
|
|
|
to run the tests and add new integration tests to make sure the features work as expected.

# Debugging
|
|
|
|
|
|
|
|
|
|
To see the generated code, set the STRUM_DEBUG environment variable before compiling your code.
|
|
|
|
|
`STRUM_DEBUG=1` will dump all of the generated code for every type. `STRUM_DEBUG=YourType` will
|
|
|
|
|
only dump the code generated on a type named `YourType`.

# Name

|
|
Strum is short for STRing enUM because it's a library for augmenting enums with additional
|
|
|
|
|
information through strings.
|
|
|
|
|
|
2017-02-12 21:52:51 +01:00
|
|
|
Strumming is also a very whimsical motion, much like writing Rust code.
