Enum UniverseInfo

pub(crate) enum UniverseInfo<'tcx> {
    RelateTys {
        expected: Ty<'tcx>,
        found: Ty<'tcx>,
    },
    TypeOp(Rc<dyn TypeOpInfo<'tcx> + 'tcx>),
    Other,
}

What operation a universe was created for.

Variants

RelateTys

Relating two types which have binders.

Fields

expected: Ty<'tcx>

found: Ty<'tcx>

TypeOp(Rc<dyn TypeOpInfo<'tcx> + 'tcx>)

Created from performing a TypeOp.

Other

Any other reason.

Implementations

impl<'tcx> UniverseInfo<'tcx>

pub(crate) fn other() -> UniverseInfo<'tcx>

pub(crate) fn relate(expected: Ty<'tcx>, found: Ty<'tcx>) -> UniverseInfo<'tcx>

pub(crate) fn report_error( &self, mbcx: &mut MirBorrowckCtxt<'_, '_, 'tcx>, placeholder: PlaceholderRegion, error_element: RegionElement, cause: ObligationCause<'tcx>, )

Trait Implementations

impl<'tcx> Clone for UniverseInfo<'tcx>

fn clone(&self) -> UniverseInfo<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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.
