This method tests for self
and other
values to be equal, and is used
by ==
.
This method tests for !=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.
This method returns an ordering between
self
and
other
values if one exists.

The direct usage of try_from("string")
is discouraged as it will produce the wrong result for values
obtained from core.bool-implicit-true
, which have no separator and are implicitly true.
This method chooses to work correctly for core.bool-empty=
, which is an empty string and resolves
to being false
.
Instead of this, obtain booleans with config.boolean(…)
, which handles the case were no separator is
present correctly.
