=head1 NAME

OpenTracing::Implementation::NoOp::Tracer - NoOp, so code won't break!

=head1 DESCRIPTION

Objects of this class implement the required methods of the
L<OpenTracing::Interface::Tracer>, to be compliant during testing and allow
applications to continue working without having to catch exceptions all the
time.

None of the methods will do anything useful.
