```
decode_field(response, type, options \\ [])
@spec decode_field(binary(), :bytes | :string, [
        field_option()
      ]) ::
        {:ok, binary()} | {:error, LibTmux.Error.t()}

decode_field(response, type, options \\ [])
@spec decode_field(binary(), :integer, [field_option()]) ::
        {:ok, integer()} | {:error, LibTmux.Error.t()}

decode_field(response, type, options \\ [])
@spec decode_field(binary(), :boolean, [field_option()]) ::
        {:ok, boolean()} | {:error, LibTmux.Error.t()}
```

Removes one framing newline and validates the complete field value.

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