🔬 This is a nightly-only experimental API. (rustc_private)

Information about the formal type/lifetime parameters associated with an item or method. Analogous to hir::Generics.

Fields

parent: Option<DefId>

🔬 This is a nightly-only experimental API. (rustc_private)

parent_regions: u32

🔬 This is a nightly-only experimental API. (rustc_private)

parent_types: u32

🔬 This is a nightly-only experimental API. (rustc_private)

regions: Vec<RegionParameterDef>

🔬 This is a nightly-only experimental API. (rustc_private)

types: Vec<TypeParameterDef>

🔬 This is a nightly-only experimental API. (rustc_private)

type_param_to_index: BTreeMap<DefIndex, u32>

🔬 This is a nightly-only experimental API. (rustc_private)

Reverse map to each TypeParameterDef's index field, from def_id.index (def_id.krate is the same as the item's).
