Returns a list of all drivers that are known to the system.

If a |driver_filter| is provided, the returned list will be filtered to

only include drivers specified in the filter.

|iterator| is closed with following epitaphs on error:

ZX_ERR_NOT_FOUND indicates that there is no driver matching the given path for at least

one driver in |driver_filter|.

ZX_ERR_BUFFER_TOO_SMALL indicates that the driver's bind program is longer than the

maximum number of instructions (BIND_PROGRAM_INSTRUCTIONS_MAX).

Returns a list of all composite node specs that are known to the system.

If a |name_filter| is provided, the returned list will only include 1 spec,

the one with that exact name.

|iterator| is closed with following epitaphs on error:

ZX_ERR_NOT_FOUND indicates that there are no specs or if a |name_filter| is provided,

that there are no specs with that name.

Returns the list of nodes that are running on the system.

If a |node_filter| is provided, the returned list will be filtered to

only include nodes specified in the filter. If |exact_match| is true,

then the filter must exactly match a node's topological path;

otherwise, it performs a substring match. The list will be empty if no

nodes match the filter.

|iterator| is closed with following epitaphs on error:

ZX_ERR_BAD_PATH indicates that the given path is not valid.

ZX_ERR_BUFFER_TOO_SMALL indicates either that the given path is too long,

or that the node has more than the maximum number of properties (PROPERTIES_MAX).

Returns the list of composites in the system. This includes composites

that are not yet assembled and added into the node topology.

Returns a list of all driver hosts that are known to the system.

Restarts all driver hosts containing the driver specified by the `driver_url`,

and returns the number of driver hosts that were restarted.

The |rematch_flags| will be used to decide for which restarting nodes the existing driver

should be bound vs. for which ones the matching process should be performed again.

Disables the driver with the given driver component url.

Disabled drivers will not be considered for matching to nodes.

If a |package_hash| is provided, only that specific version of the driver

package will be disabled. Otherwise this applies to all existing versions

of a driver with the given url.

Returns an error ZX_ERR_NOT_FOUND if no drivers were affected.

Enables the driver with the given driver component url.

This is only meant to revert a |DisableDriver| action.

Returns an error ZX_ERR_NOT_FOUND if no drivers were affected.

Attempts to bind all unbound nodes in the topology.

Returns new successful binds.

Attempts to bind all unbound nodes in the topology.

Returns new successful binds.

Adds test node under the root node.

Removes the test node. The node is removed asynchronously and is

not guaranteed to be removed by the time this returns.

Waits for bootup to complete.

Restarts the driver components bound to the nodes identified in |node_ids|,

providing them with the given dictionary. All child nodes are also restarted

and provided with this dictionary. This operation is temporary and

is reversed by releasing the |release_fence| that is returned.

Restarts the driver components bound to the node identified by |moniker|,

providing it with the given dictionary and power dependencies.

All child nodes are also restarted and provided with the dictionary,

but only the node identified by |moniker| will be provided with the

power dependencies. An empty vector of power dependencies results in

the driver's power element having no dependencies other than a

dependency on CPU. The |cpu_token_override| will be used as the token

for making dependencies on the CPU power element. This override remains

in place for all restarted drivers until the fence is released.

The effects of this call are temporary and are reversed by releasing

the |release_fence| that is returned.

TODO(https://fxbug.dev/494673577) Consolidate this API with

`RestartWithDictionary`.

Rebinds any composites and composite specs that have the given driver_url. This means the

spec is rematched with possibly another driver, or none if the only matching driver is

disabled, and any active nodes created from this spec are removed and re-bound.

Returns the number of affected composite nodes.
