Abstract Value Members

  1. abstract def hash(a: A): Int

    Returns the hash of the specified value.

Concrete Value Members

  1. final def both[B](that: => Equal[B]): Equal[(A, B)]

    Constructs an Equal[(A, B)] given an Equal[A] and Equal[B] by first comparing the A values for equality and then comparing the B values for equality, if necessary.

    Constructs an Equal[(A, B)] given an Equal[A] and Equal[B] by first comparing the A values for equality and then comparing the B values for equality, if necessary.

    Equal
  2. final def bothWith[B, C](that: => Equal[B])(f: (C) => (A, B)): Equal[C]

    Constructs an Equal[C] given an Equal[A], an Equal[B] and a function f to transform a C value into an (A, B).

    Constructs an Equal[C] given an Equal[A], an Equal[B] and a function f to transform a C value into an (A, B). The instance will convert each C value into an (A, B), compare the A values for equality, and then compare the B values for equality if necessary.

    Definition Classes
    Equal
  3. def contramap[B](f: (B) => A): Hash[B]

    Constructs a Hash[B] given a Hash[A] and a function f to transform a B value into an A value.

    Constructs a Hash[B] given a Hash[A] and a function f to transform a B value into an A value. The instance will convert each B value into an A and hash the A values.

    Hash → Equal
  4. final def either[B](that: => Equal[B]): Equal[Either[A, B]]

    Constructs an Equal[Either[A, B]] given an Equal[A] and an Equal[B].

    Constructs an Equal[Either[A, B]] given an Equal[A] and an Equal[B]. The instance will compare the Either[A, B] values and if both are Right or Left compare them for equality.

    Definition Classes
    Equal
  5. final def eitherWith[B, C](that: => Equal[B])(f: (C) => Either[A, B]): Equal[C]

    Constructs an Equal[C] given an Equal[A], an Equal[B], and a function f to transform a C value into an Either[A, B].

    Constructs an Equal[C] given an Equal[A], an Equal[B], and a function f to transform a C value into an Either[A, B]. The instance will convert each C value into an Either[A, B] and then if both are Right or Left compare them for equality.

  6. final def equal(l: A, r: A): Boolean

    Returns whether two values of type A are equal.

    Returns whether two values of type A are equal.

  7. final def notEqual(l: A, r: A): Boolean

    Returns whether two values of type A are not equal.

    Returns whether two values of type A are not equal.
