Patterns

Pattern matching with literals, tuples, structs, named tuples, wildcards, and mutable bindings.

// Literal patterns
match x {
    1 => "one",
    2 => "two",
    _ => "other",
}

// Tuple patterns
let (a, b) = (1, 2);

// Struct patterns
match value {
    Point { x, y } => x + y,
    Point { x: 0, y } => y,
    _ => 0,
}

// Named tuple patterns (newtype)
let MyType(value) = my_var;

// Wildcard / rest
let _ = get_side_effect();
match x {
    1 => expr,
    .. => expr,  // rest / etc
}

// Mutable binding in pattern
let mut x = 42;
match ref_to_option {
    Some(mut value) => value += 1,
    None => {},
}

Modules & Imports
