Enum GenericArg

pub enum GenericArg<'hir> {
    Lifetime(&'hir Lifetime),
    Type(&'hir Ty<'hir>),
    Const(&'hir ConstArg<'hir>),
    Infer(InferArg),
}

Variants

Lifetime(&'hir Lifetime)

Type(&'hir Ty<'hir>)

Const(&'hir ConstArg<'hir>)

Infer(InferArg)

Note: Inference variables are only represented as GenericArg::Infer in cases where it is ambiguous whether a generic arg is a type or a const. Otherwise, inference variables are represented as TyKind::Infer or ConstArgKind::Infer.

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.
