Fields

binding_mode: BindingMode

Is variable bound via x, mut x, ref x, or ref mut x?

opt_ty_info: Option<Span>

If an explicit type was provided for this variable binding, this holds the source Span of that type.

NOTE: If you want to change this to a HirId, be wary that doing so breaks incremental compilation (as of this writing), while a Span does not cause our tests to fail.
