OpenTracing::Implementation::NoOp - Stops Crashing, doing nothing else
use OpenTracing::Implementation::NoOp; my $tracer = OpenTracing::Implementation::NoOp->bootstrap_tracer( );
The NoOp Implementation will 'disable' the entire OpenTracing infrastructure by making almost every method do nothing, or return a 'NoOp' object.
This way, none of the code will break if there is no OpenTracing active.
This implementation does not rely on OpenTracing::Role, because those already add attributes and methods that are totally useless in this context of a 'NoOp'. Instead, this only requires the OpenTrace::Interface if the OPENTRACING_INTERFACE environment variable has been set (for development purposes).
OPENTRACING_INTERFACE
my $tracer = OpenTracing::Implementation::NoOp->bootstrap_tracer( @args );
Returns a OpenTracing::Interface::Tracer compliant tracer, using the OpenTracing::Implementation::NoOp::Tracer implementation.
Any arguments passed in, are dutyfully passed, but are supposedly useless.
If set to true, this will wrap all methods inside Type::Tiny typechecks, for incomming parameters and return values. Beside that, it will add check for required methods according to the OpenTracing::Interface API description.
