Required Methods

fn def_id(self) -> <I as Interner>::DefId

fn is_struct(self) -> bool

fn struct_tail_ty( self, interner: I, ) -> Option<EarlyBinder<I, <I as Interner>::Ty>>

Returns the type of the struct tail.

Expects the AdtDef to be a struct. If it is not, then this will panic.

fn is_phantom_data(self) -> bool

fn all_field_tys( self, interner: I, ) -> EarlyBinder<I, impl IntoIterator<Item = <I as Interner>::Ty>>

fn sized_constraint( self, interner: I, ) -> Option<EarlyBinder<I, <I as Interner>::Ty>>

fn is_fundamental(self) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
