Used to configure inference contexts before their creation
Whether we are in coherence mode.
normalize_fn_sig_for_diagnostic: Option<Lrc<dyn Fn(&InferCtxt<'tcx>, PolyFnSig<'tcx>) -> PolyFnSig<'tcx>>>
InferCtxt should be able to handle defining uses of opaque types,
you need to call this function. Otherwise the opaque type will be treated opaquely.
It is only meant to be called in two places, for typeck
Inherited::build) and for the inference context used
in mir borrowck.
Given a canonical value
C as a starting point, create an
inference context that contains each of the bound values
within instantiated as a fresh variable. The
f closure is
invoked with the new infcx, along with the instantiated value
V and a substitution
S. This substitution
S maps from
the bound values in
C to their instantiated values in
(in other words,
S(C) = V).
