# `RustQ.Syn.Impl`
[🔗](https://github.com/elixir-crab/rustq/blob/v1.0.0-rc.19/lib/rustq/syn.ex#L618)

Rust impl block metadata, including target type, optional trait, doc comments, and methods.

`trait_ast` is the implemented trait's path, and `negative` marks an impl such as
`impl !Send for T`. `bounds` pairs each of the impl's `type_parameters` with the traits bounding it, inline or
in the where clause, named by the last segment of their path. `types` pairs each associated
type the impl defines with its type, as in `{"Target", [T]}` for a `Deref` impl.

# `t`

```elixir
@type t() :: %RustQ.Syn.Impl{
  bounds: [{String.t(), [String.t()]}],
  docs: [String.t()],
  methods: [RustQ.Syn.Method.t()],
  negative: boolean(),
  source_line: pos_integer() | nil,
  source_path: Path.t() | nil,
  target: String.t(),
  target_ast: RustQ.Syn.type(),
  trait: String.t() | nil,
  trait_ast: RustQ.Syn.Type.Path.t() | nil,
  type_parameters: [String.t()],
  types: [{String.t(), RustQ.Syn.type()}]
}
```
