Trait ToTrace 

pub trait ToTrace<'tcx>: Relate<TyCtxt<'tcx>> + Copy {
    // Required method
    fn to_trace(
        cause: &ObligationCause<'tcx>,
        a: Self,
        b: Self,
    ) -> TypeTrace<'tcx>;
}

Required Methods

fn to_trace(cause: &ObligationCause<'tcx>, a: Self, b: Self) -> TypeTrace<'tcx>

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.
