static VALUE
true_and(VALUE obj, VALUE obj2)
{
return RBOOL(RTEST(obj2));
}
And—Returns false
if obj is nil
or false
, true
otherwise.
#define case_equal rb_equal
Case Equality – For class Object
, effectively the same as calling #==
, but typically overridden by descendants to provide meaningful semantics in case

static VALUE
true_xor(VALUE obj, VALUE obj2)
{
return rb_obj_not(obj2);
}
Exclusive Or—Returns true
if obj is nil
or false
, false
otherwise.
MJIT_FUNC_EXPORTED VALUE
rb_true_to_s(VALUE obj)

return rb_cTrueClass_to_s;
}
The string representation of true
is “true”.
static VALUE
true_or(VALUE obj, VALUE obj2)
{
return Qtrue;
}
