Expand description

Represents lifetimes and type parameters attached to a declaration of a function, enum, trait, etc.

Fields

params: &'hir [GenericParam<'hir>]predicates: &'hir [WherePredicate<'hir>]has_where_clause_predicates: boolwhere_clause_span: Spanspan: Span

Implementations

If there are generic parameters, return where to introduce a new one.

Span where further predicates would be suggested, accounting for trailing commas, like in fn foo<T>(t: T) where T: Foo, so we don’t suggest two trailing commas.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Performs the conversion.

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.
