### Type Members

1. #### final class AToBEquivalenceConstraint[A, B] extends CanEqual[A, B]

An implementation of Constraint for two types A and B that requires an Equality[B] and a conversion function from A to B.

An implementation of Constraint for two types A and B that requires an Equality[B] and a conversion function from A to B.

2. #### final class BToAEquivalenceConstraint[A, B] extends CanEqual[A, B]

An implementation of Constraint for two types A and B that requires an Equality[A] and a conversion function from B to A.

An implementation of Constraint for two types A and B that requires an Equality[A] and a conversion function from B to A.

3. #### final class EqualityConstraint[A, B] extends CanEqual[A, B]

An implementation of Constraint for two types A and B that requires an Equality[A] to which its areEqual method can delegate an equality comparison.

An implementation of Constraint for two types A and B that requires an Equality[A] to which its areEqual method can delegate an equality comparison.

4. #### final case class Spread[T](pivot: T, tolerance: T)(implicit evidence\$1: Numeric[T]) extends Product with Serializable

Class representing an spread (i.e., range) between two numbers.

Class representing an spread (i.e., range) between two numbers.

The spread is expressed in terms of a Numeric pivot and tolerance. The spread extends from pivot - tolerance to pivot + tolerance, inclusive.

pivot

the pivot number at the center of the spread

tolerance

the tolerance that determines the high and low point of the spread

5. #### final case class TripleEqualsInvocation[T](right: T, expectingEqual: Boolean) extends Product with Serializable

Facilitates the “should ===” and “should !==” syntax of ScalaTest's matchers DSL.

Facilitates the “should ===” and “should !==” syntax of ScalaTest's matchers DSL.

Instances of this class are created and returned by the === and !== methods of trait TripleEqualsSupport.

right

the right-hand side value for an equality assertion

expectingEqual

true if the result of a === invocation; false if the result of a !== invocation.

Facilitates the “should === (x += y)” and “should !== (x += y)” syntax of ScalaTest's matchers DSL.

the Spread[T] against which to compare the left-hand value

expectingEqual

true if the result of a === invocation; false if the result of a !== invocation.
