Struct rustc_middle::traits::ImplSourceUserDefinedData

pub struct ImplSourceUserDefinedData<'tcx, N> {
    pub impl_def_id: DefId,
    pub substs: SubstsRef<'tcx>,
    pub nested: Vec<N>,
}

Identifies a particular impl in the source, along with a set of substitutions from the impl’s type/lifetime parameters. The nested vector corresponds to the nested obligations attached to the impl’s type parameters.

The type parameter N indicates the type used for “nested obligations” that are required by the impl. During type-check, this is Obligation, as one might expect. During codegen, however, this is (), because codegen only requires a shallow resolution of an impl, and nested obligations are satisfied later.

fn eq(&self, other: &ImplSourceUserDefinedData<'tcx, N>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ImplSourceUserDefinedData<'tcx, N>) -> bool

This method tests for !=.

impl<'tcx, N> TypeFoldable<'tcx> for ImplSourceUserDefinedData<'tcx, N> where
    N: TypeFoldable<'tcx>, 

fn super_fold_with<__F: TypeFolder<'tcx>>(self, __folder: &mut __F) -> Self

fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool

Returns true if self has any late-bound regions that are either bound by binder or bound by some binder outside of binder. If binder is ty::INNERMOST, this indicates whether there are any late-bound regions that appear free.

fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool

Returns true if this self has any regions that escape binder (and hence are not bound by it).

fn has_escaping_bound_vars(&self) -> bool

fn has_type_flags(&self, flags: TypeFlags) -> bool

fn has_projections(&self) -> bool

fn has_param_types_or_consts(&self) -> bool

fn has_infer_regions(&self) -> bool

fn has_infer_types(&self) -> bool

fn has_infer_types_or_consts(&self) -> bool

fn needs_infer(&self) -> bool

fn has_placeholders(&self) -> bool

fn needs_subst(&self) -> bool

fn has_free_regions(&self) -> bool

“Free” regions in this context means that it has any region that is not (a) erased or (b) late-bound.

fn has_erased_regions(&self) -> bool

fn has_erasable_regions(&self) -> bool

True if there are any un-erased free regions.

fn is_global(&self) -> bool

Indicates whether this value references only ‘global’ generic parameters that are the same regardless of what fn we are in. This is used for caching.

fn has_late_bound_regions(&self) -> bool

True if there are any late-bound regions

fn still_further_specializable(&self) -> bool

Indicates whether this value still has parameters/placeholders/inference variables which could be replaced later, in a way that would change the results of impl specialization.
