TrueClass

And—Returns false if obj is nil or false, true otherwise.

 
               static VALUE
true_and(VALUE obj, VALUE obj2)
{
    return RBOOL(RTEST(obj2));
}
            

Case Equality – For class Object, effectively the same as calling #==, but typically overridden by descendants to provide meaningful semantics in case statements.

 
               #define case_equal rb_equal
            

Exclusive Or—Returns true if obj is nil or false, false otherwise.

 
               static VALUE
true_xor(VALUE obj, VALUE obj2)
{
    return RTEST(obj2)?Qfalse:Qtrue;
}
            

The string representation of true is “true”.

 
               MJIT_FUNC_EXPORTED VALUE
rb_true_to_s(VALUE obj)
{
    return rb_cTrueClass_to_s;
}
            

Or—Returns true. As obj is an argument to a method call, it is always evaluated; there is no short-circuit evaluation in this case.

true |  puts("or")
true || puts("logical or")

produces:

or

 
               static VALUE
true_or(VALUE obj, VALUE obj2)
{
    return Qtrue;
}
