Module sp_arithmetic::traits

Primitives for the runtime modules.

Traits

Bounded	Numbers which have upper and lower bounds
CheckedAdd	Performs addition that returns None instead of wrapping around on overflow.
CheckedDiv	Performs division that returns None instead of panicking on division by zero and instead of wrapping around on underflow and overflow.
CheckedMul	Performs multiplication that returns None instead of wrapping around on underflow or overflow.
CheckedShl	Performs a left shift that returns None on shifts larger than the type width.
CheckedShr	Performs a right shift that returns None on shifts larger than the type width.
CheckedSub	Performs subtraction that returns None instead of wrapping around on underflow.
IntegerSquareRoot	A trait implementing integer square root.
One	Defines a multiplicative identity element for Self.
SaturatedConversion	Convenience type to work around the highly unergonomic syntax needed to invoke the functions of overloaded generic traits, in this case SaturatedFrom and SaturatedInto.
Saturating	Simple trait to use checked mul and max value to give a saturated mul operation over supported types.
SimpleArithmetic	A meta trait for arithmetic.
UniqueSaturatedFrom	Just like From except that if the source value is too big to fit into the destination type then it'll saturate the destination.
UniqueSaturatedInto	Just like Into except that if the source value is too big to fit into the destination type then it'll saturate the destination.
Zero	Defines an additive identity element for Self.
