Required Methods

fn legacy_const_generic_args( &self, expr: &Expr, tcx: TyCtxt<'tcx>, ) -> Option<Vec<usize>>

fn extra_lifetime_params( &self, id: NodeId, ) -> &[(Ident, NodeId, MissingLifetimeKind)]

Obtain the list of lifetimes parameters to add to an item.

Extra lifetime parameters should only be added in places that can appear as a binder in LifetimeRes.

The extra lifetimes that appear from the parenthesized Fn-trait desugaring should appear at the enclosing PolyTraitRef.

fn delegation_info(&self, id: LocalDefId) -> Option<&DelegationInfo>

fn owner_def_id(&self, id: NodeId) -> LocalDefId

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
