> Decimal128 can cast to Float64 in can_coerce_from, why? Floating points inherently permit precision loss > No list coercion for can_coerce_from I think this would make sense as an addition, the current support for nested types in arrow-cast is very limited. > If lossless conversion is useful for arrow-rs In general I think it would be very confusing if coercion can result in silent data loss, perhaps you might articulate why this would be useful? My current thinking is casting should never silently lose data. -- This is an automated message from the Apache Git Service.
