NAME
       Test2::API::Instance - Object used by Test2::API under the hood
DESCRIPTION
       This object encapsulates the global shared state tracked by Test2. A
       single global instance of this package is stored (and obscured) by the
       Test2::API package.
       There is no reason to directly use this package. This package is
       documented for completeness. This package can change, or go away
       completely at any time.  Directly using, or monkeypatching this package
       is not supported in any way shape or form.
SYNOPSIS
           use Test2::API::Instance;
           my $obj = Test2::API::Instance->new;
       $pid = $obj->pid
           PID of this instance.
       $obj->tid
           Thread ID of this instance.
       $obj->reset()
           Reset the object to defaults.
       $obj->load()
           Set the internal state to loaded, and run and stored post-load
           callbacks.
       $bool = $obj->loaded
           Check if the state is set to loaded.
       $arrayref = $obj->post_load_callbacks
           Get the post-load callbacks.
       $obj->add_post_load_callback(sub { ... })
           Add a post-load callback. If "load()" has already been called then
           the callback will be immediately executed. If "load()" has not been
           called then the callback will be stored and executed later when
           "load()" is called.
       $hashref = $obj->contexts()
           Get a hashref of all active contexts keyed by hub id.
       $arrayref = $obj->context_acquire_callbacks
           Get all context acquire callbacks.
       $arrayref = $obj->context_init_callbacks
           Get all context init callbacks.
       $arrayref = $obj->context_release_callbacks
           Get all context release callbacks.
       $arrayref = $obj->pre_subtest_callbacks
           Get all pre-subtest callbacks.
       $obj->add_context_init_callback(sub { ... })
           Add a context init callback. Subs are called every time a context
           is created. Subs get the newly created context as their only
           argument.
       $obj->add_context_release_callback(sub { ... })
           Add a context release callback. Subs are called every time a
           context is released. Subs get the released context as their only
           argument. These callbacks should not call release on the context.
       $obj->add_pre_subtest_callback(sub { ... })
           Add a pre-subtest callback. Subs are called every time a subtest is
           going to be run. Subs get the subtest name, coderef, and any
           arguments.
       $obj->set_exit()
           This is intended to be called in an "END { ... }" block. This will
           look at test state and set $?. This will also call any end
           callbacks, and wait on child processes/threads.
       $obj->set_ipc_pending($val)
           Tell other processes and threads there is a pending event. $val
           should be a unique value no other thread/process will generate.
           Note: This will also make the current process see a pending event.
       $pending = $obj->get_ipc_pending()
           This returns -1 if it is not possible to know.
           This returns 0 if there are no pending events.
           This returns 1 if there are pending events.
       $timeout = $obj->ipc_timeout;
       $obj->set_ipc_timeout($timeout);
           How long to wait for child processes and threads before aborting.
       $drivers = $obj->ipc_drivers
           Get the list of IPC drivers.
       $obj->add_ipc_driver($DRIVER_CLASS)
           Add an IPC driver to the list. The most recently added IPC driver
           will become the global one during initialization. If a driver is
           added after initialization has occurred a warning will be
           generated:
               "IPC driver $driver loaded too late to be used as the global ipc driver"
       $bool = $obj->ipc_polling
           Check if polling is enabled.
       $obj->enable_ipc_polling
           Turn on polling. This will cull events from other processes and
           threads every time a context is created.
       $obj->disable_ipc_polling
           Turn off IPC polling.
       $bool = $obj->no_wait
       $bool = $obj->set_no_wait($bool)
           Get/Set no_wait. This option is used to turn off process/thread
           waiting at exit.
       $arrayref = $obj->exit_callbacks
           Get the exit callbacks.
       $obj->add_exit_callback(sub { ... })
           Add an exit callback. This callback will be called by "set_exit()".
       $bool = $obj->finalized
           Check if the object is finalized. Finalization happens when either
           "ipc()", "stack()", or "format()" are called on the object. Once
           finalization happens these fields are considered unchangeable (not
           enforced here, enforced by Test2).
       $ipc = $obj->ipc
           Get the one true IPC instance.
       $obj->ipc_disable
           Turn IPC off
       $bool = $obj->ipc_disabled
           Check if IPC is disabled
       $stack = $obj->stack
           Get the one true hub stack.
       $formatter = $obj->formatter
           Get the global formatter. By default this is the
           'Test2::Formatter::TAP' package. This could be any package that
           implements the "write()" method. This can also be an instantiated
           object.
       $bool = $obj->formatter_set()
           Check if a formatter has been set.
       $obj->add_formatter($class)
       $obj->add_formatter($obj)
           Add a formatter. The most recently added formatter will become the
           global one during initialization. If a formatter is added after
           initialization has occurred a warning will be generated:
               "Formatter $formatter loaded too late to be used as the global formatter"
       $obj->set_add_uuid_via(sub { ... })
       $sub = $obj->add_uuid_via()
           This allows you to provide a UUID generator. If provided UUIDs will
           be attached to all events, hubs, and contexts. This is useful for
           storing, tracking, and linking these objects.
           The sub you provide should always return a unique identifier. Most
           things will expect a proper UUID string, however nothing in
           Test2::API enforces this.
           The sub will receive exactly 1 argument, the type of thing being
           tagged 'context', 'hub', or 'event'. In the future additional
           things may be tagged, in which case new strings will be passed in.
           These are purely informative, you can (and usually should) ignore
           them.
