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:

-
#<(other : T)
Compares this object to other based on the receiver’s
<=>method, returningtrueif it returns-1. -
#<=(other : T)
Compares this object to other based on the receiver’s
<=>method, returningtrueif it returns-1or0. -
#==(other : T)
Compares this object to other based on the receiver’s
<=>method, returningtrueif it returns0. -
#>(other : T)
Compares this object to other based on the receiver’s
<=>method, returningtrueif it returns1. -
#>=(other : T)
Compares this object to other based on the receiver’s
<=>method, returningtrueif it returns1or0. - #compare_with(other : T, &block)
Instance Method Detail
Compares this object to other based on the receiver’s <=> method, returning true if it returns -1.
Compares this object to other based on the receiver’s <=> method, returning true if it returns -1 or 0.
Compares this object to other based on the receiver’s <=> method, returning true if it returns 0.
Also returns true if this and other are the same object.
Compares this object to other based on the receiver’s <=> method, returning true if it returns 1.
Compares this object to other based on the receiver’s <=> method, returning true if it returns 1 or 0.
