Fields§

§db: &'a dyn HirDatabase§type_param_mode: ParamLoweringMode

Note: Conceptually, it’s thinkable that we could be in a location where some type params should be represented as placeholders, and others should be converted to variables. I think in practice, this isn’t possible currently, so this should be fine for now.
