Trait FromCycleError 

pub(crate) trait FromCycleError<'tcx>: Sized {
    // Required method
    fn from_cycle_error(
        tcx: TyCtxt<'tcx>,
        cycle_error: CycleError,
        guar: ErrorGuaranteed,
    ) -> Self;
}

Required Methods

fn from_cycle_error( tcx: TyCtxt<'tcx>, cycle_error: CycleError, guar: ErrorGuaranteed, ) -> Self

Try to produce a Self value that represents an error form (e.g. TyKind::Error).

Note: the default impl calls raise_fatal, ending compilation immediately! Only a few types override this with a non-fatal impl.

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.
