# `WardrikRest.Parameter`

One argument of an operation: part of its path, its query, a field of its body, the whole
body, or a header.

  * `in: :body` - one field of an object body, with the operation's other `:body` fields.
  * `in: :payload` - the whole body, for a body that isn't an object of fields.

`:schema` is a JSON Schema, which may refer to the spec's types. A path parameter with
`reserved: true` keeps its `/`s, as `properties/123`.

# `t`

```elixir
@type t() :: %WardrikRest.Parameter{
  in: :path | :query | :body | :payload | :header,
  name: String.t(),
  required: boolean(),
  reserved: boolean(),
  schema: map()
}
```
