```
validate(value, options \\ [])
@spec validate(term(), [LibTmux.Filter.limit_option()]) ::
        {:ok, value()} | {:error, LibTmux.Error.t()}
```

Validates already-decoded JSON data and its complete encoded byte size.

Arrays must be proper lists; a malformed tail reports the containing
array's path. An excess prefix returns the list limit before inspecting its tail.

See the [worked example](api-examples.html#encoding-and-protocol).

## Parameters

- `value` (`term()`)
- `options` (`[LibTmux.Filter.limit_option()]`)
