module PartialComparable(T)

Overview

The PartialComparable mixin is used by classes whose objects may be partially ordered.

Including types must provide an <=> method, which compares the receiver against another object, returning -1, 0, +1 or nil depending on whether the receiver is less than, equal to, greater than the other object, or no order can be established.

PartialComparable uses <=> to implement the conventional comparison operators (#<, #<=, #==, #>=, and #>).

Defined in:

Instance Method Summary

• #<(other : T)

  Compares this object to other based on the receiver’s <=> method, returning true if it returns -1.

• #<=(other : T)

  Compares this object to other based on the receiver’s <=> method, returning true if it returns -1 or 0.

• #==(other : T)

  Compares this object to other based on the receiver’s <=> method, returning true if it returns 0.

• #>(other : T)

  Compares this object to other based on the receiver’s <=> method, returning true if it returns 1.

• #>=(other : T)

  Compares this object to other based on the receiver’s <=> method, returning true if it returns 1 or 0.

• #compare_with(other : T, &block)
