template <typename A>struct SliceCastable
Defined at line 36 of file ../../third_party/grpc-migrating/src/include/grpc/event_engine/internal/slice_cast.h
This is strictly too wide, but consider all types to be SliceCast-able to
themselves.
Unfortunately this allows `const int
&
x = SliceCast
<int
>(x);` which is kind
of bogus.
