# `Lumis.Decoration.RainbowBracket`
[🔗](https://github.com/leandrocp/lumis/blob/hex-lumis/v0.10.0/packages/elixir/lumis/lib/lumis/decoration.ex#L1)

A matched bracket carrying its real zero-based nesting depth.

Built-in formatters cycle this depth through six theme scopes. Custom
formatters receive the unwrapped value between `:decoration_start` and
`:decoration_end` events.

# `t`

```elixir
@type t() :: %Lumis.Decoration.RainbowBracket{depth: non_neg_integer()}
```
