Struct ra_ap_hir_ty::TyLoweringContext

pub struct TyLoweringContext<'a> {
    pub db: &'a dyn HirDatabase,
    pub type_param_mode: ParamLoweringMode,
    /* private fields */
}

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.
