This trait is used to provide supertraits to the Fixed trait depending
on the crate’s optional features, and should not be used directly.
If the num-traits experimental feature is enabled, the following are
supertraits of Fixed:
ZeroBoundedCheckedAdd,CheckedSub,CheckedNeg,CheckedMul,CheckedRem,CheckedShl,CheckedShrSaturatingAdd,SaturatingSub,SaturatingMulWrappingAdd,WrappingSub,WrappingNeg,WrappingMul,WrappingShl,WrappingShrOverflowingAdd,OverflowingSub,OverflowingMulToPrimitive,FromPrimitiveFloatConst
The following are supertraits of FixedStrict as they have extra
constraints:
The following are not supertraits of Fixed or FixedStrict, even
though they are implemented for fixed-point numbers where applicable:
Onebecause not all fixed-point numbers can represent the value 1Numbecause it hasOneas a supertraitMulAdd,MulAddAssignbecauseMulAdd::mul_addconflicts withFixed::mul_add
Similarly, Signed and Unsigned are not supertraits of
FixedSigned and FixedUnsigned because they have Num as a
supertrait.
