Variants

CodeCycle(Vec<PredicateObligation<'tcx>>)

Inherently impossible to fulfill; this trait is implemented if and only if it is already implemented.

CodeSelectionError(SelectionError<'tcx>)

CodeProjectionError(MismatchedProjectionTypes<'tcx>)

CodeSubtypeError(ExpectedFound<Ty<'tcx>>, TypeError<'tcx>)

CodeConstEquateError(ExpectedFound<Const<'tcx>>, TypeError<'tcx>)

CodeAmbiguity

Fields

overflow: bool

Overflow reported from the new solver -Ztrait-solver=next, which will be reported as an regular error as opposed to a fatal error.

Trait Implementations

impl<'tcx> Clone for FulfillmentErrorCode<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for FulfillmentErrorCode<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
