Returns true if x and y are equivalent, false otherwise.
Returns true if x and y are equivalent, false otherwise.
Returns false if x and y are equivalent, true otherwise.
Returns false if x and y are equivalent, true otherwise.
Defines an order on B by mapping B to A using f and using As
order to order B.
Defines an order on B by mapping B to A using f and using As
order to order B.
Result of comparing x with y.
Result of comparing x with y. Returns ValidIO[ComparisonBundle]
with valid false if operands are not comparable. If operands are
comparable, bits.lt will be true if x < y and bits.eq will
be true if x = y
Returns Some(x) if x >= y, Some(y) if x < y, otherwise None.
Returns Some(x) if x >= y, Some(y) if x < y, otherwise None.
Returns Some(x) if x <= y, Some(y) if x > y, otherwise None.
Returns Some(x) if x <= y, Some(y) if x > y, otherwise None.

The
Ordertype class is used to define a total ordering on some typeA. An order is defined by a relation <=, which obeys the following laws:- either x <= y or y <= x (totality) - if x <= y and y <= x, then x == y (antisymmetry) - if x <= y and y <= z, then x <= z (transitivity)
The truth table for compare is defined as follows:
x <= y x >= y Int true true = 0 (corresponds to x == y) true false < 0 (corresponds to x < y) false true > 0 (corresponds to x > y)
By the totality law, x <= y and y <= x cannot be both false.
