Public Methods

void Bind (Node & node, std::shared_ptr<BindResultTracker> result_tracker)

Attempt to bind `node`.

A nullptr for result_tracker is acceptable if the caller doesn't intend to

track the results.

void CreateDriverHostDynamicLinker (std::string_view driver_name_name_for_colocation, fit::callback<void (zx::result<DriverHost *>)> completion_cb)

Creates the driver host component, loads the driver host using dynamic linking,

and calls |cb| on completion or error.

void DestroyDriverHostComponent (std::string_view driver_host_name_for_colocation, fit::callback<void (zx::result<>)> completion_cb)

Destroys the driver host component asynchronously. Calls |cb| on completion.

bool IsDriverHostValid (DriverHost * driver_host)

DriverHost lifetimes are managed through a linked list, and they will delete themselves

when the FIDL connection is closed. Currently in the Node class we store a raw pointer to the

DriverHost object, and do not have a way to remove it from the class when the underlying

DriverHost object is deallocated. This function will return true if the underlying DriverHost

object is still alive and in the linked list. Otherwise returns false.

Create a power element where |element_token| is the access token for the newly created

element. |deps| are the tokens this element should depend on.

|cb| is called with:

- `zx::ok(true)` if the power element was successfully created

- `zx::ok(false)` if the power element could not be created because this is not a suspend-

enabled platform.

- `zx::error` if an error happens creating the element on a suspend-enabled platform.

void AddLeaseControlChannel (fidl::ClientEnd<fuchsia_power_broker::LeaseControl> lease)

Store the `fuchsia.power.broker/LeaseControl` channel associated with the power element for

this element.
