# Rainbow Brackets

```elixir
Mix.install([
  {:lumis, "~> 0.3"}
])
```

## Example

Rainbow brackets use each language's Tree-sitter `brackets.scm` query. The Rust query includes `()`, `[]`, `{}`, `< >`, and closure pipes, and excludes string delimiters from rainbow coloring.

```elixir
code = ~S'''
fn main() {
    let foo = OptionalI32::AnI32(1);
    match foo {
        OptionalI32::AnI32(n) => println!("it is an i32: {}", n),
        OptionalI32::Nothing => println!("it is nothing!"),
    }
}
'''
