# Other style advice

## Expressions

Prefer to use Rust’s expression oriented nature where possible;

    #![allow(unused)]
    fn main() {
    // use
    let x = if y { 1 } else { 0 };
    // not
    let x;
    if y {
        x = 1;
    } else {
        x = 0;
    }
    }

## Names

- Types shall be `UpperCamelCase`,
- Enum variants shall be `UpperCamelCase`,
- Struct fields shall be `snake_case`,
- Function and method names shall be `snake_case`,
- Local variables shall be `snake_case`,
- Macro names shall be `snake_case`,
- Constants (`const`s and immutable `static`s) shall be `SCREAMING_SNAKE_CASE`.
- When a name is forbidden because it is a reserved word (such as `crate`), either use a raw identifier (`r#crate`) or use a trailing underscore (`crate_`). Don’t misspell the word (`krate`).

### Modules

Avoid `#[path]` annotations where possible.
