# Rust

To use this language, use the class "language-rust".

## Comments

    // Single line comment
    /// Doc comments
    /* Multiline
    comment */

## Strings

    'C'; '\''; '\n'; '\u7FFF'; // Characters
    "foo \"bar\" baz"; // String
    r##"foo #"bar"# baz"##; // Raw string with # pairs
    b'C'; b'\''; b'\n'; // Bytes
    b"foo \"bar\" baz"; // Byte string
    br##"foo #"bar"# baz"##; // Raw byte string with # pairs

## Numbers

    123i;                              // type int
    123u;                              // type uint
    123_u;                             // type uint
    0xff_u8;                           // type u8
    0o70_i16;                          // type i16
    0b1111_1111_1001_0000_i32;         // type i32

    123.0f64;        // type f64
    0.1f64;          // type f64
    0.1f32;          // type f32
    12E+99_f64;      // type f64

## Booleans

    true; false;

## Functions and macros

    println!("x is {}", x);
    fn next_two(x: int) -> (int, int) { (x + 1i, x + 2i) }
    next_two(5i);
    vec![1i, 2, 3];

## Attributes

    #![warn(unstable)]
    #[test]
    fn a_test() {
    	// ...
    }

## Closure parameters and bitwise OR

    let x = a | b;
    let y = c || d;
    let add_one = |x: int| -> int { 1i + x };
    let printer = || { println!("x is: {}", x); };

## Known failures

There are certain edge cases where Prism will fail. There are always such cases in every regex-based syntax highlighter. However, Prism dares to be open and honest about them. If a failure is listed here, it doesn’t mean it will never be fixed. This is more of a “known bugs” list, just with a certain type of bug.

### Nested block comments

    /* Nested block
    	/* comments
    	are */
    not supported */

### Delimiters of parameters for closures that don't use braces

    |x| x + 1i;
