Fix direct access to the inner specific formatted values
This is no longer available as this could lead to building a defined
value in Rust which could be interpreted as undefined in C due to
the sentinel u64::MAX
for None
.
Use the constants (e.g. ONE
, K
, M
, ...) and operations to build
a value and deref (*
) to get the quantity as an integer.
