Struct rustc_middle::ty::GenericParamDef

pub struct GenericParamDef {
    pub name: Symbol,
    pub def_id: DefId,
    pub index: u32,
    pub pure_wrt_drop: bool,
    pub kind: GenericParamDefKind,

Fields

name: Symbol

def_id: DefId

index: u32

pure_wrt_drop: bool

pure_wrt_drop, set by the (unsafe) #[may_dangle] attribute on generic parameter 'a/T, asserts data behind the parameter 'a/T won’t be accessed during the parent type’s Drop impl.

kind: GenericParamDefKind

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
