struct RenderingProcessAn object that represents a running GPU extension process. The system guarantees that the extension process has launched by the time any init methods return. If the extension process exits, the system calls ``onInterruption``. There can only be one extension process per host browser. The first time this type is initialized, a process will be launched. If an extension process is all ready running, the returned object will represent the already running process.
invalidate(): voidfunc invalidate()Stops the extension process. When you call this method, you tell the system your app no longer needs this extension process. If this is the last connection from the host process to the extension process, the system terminates the extension process.
grantCapabilityInvalidationHandler(capability: ProcessCapability, invalidationHandler: (() => void)): ProcessCapability_Grantfunc grantCapability(_ capability: ProcessCapability, invalidationHandler: @escaping () -> Void) throws -> ProcessCapability.GrantgrantCapability(capability: ProcessCapability): ProcessCapability_Grantfunc grantCapability(_ capability: ProcessCapability) throws -> ProcessCapability.GrantGrants the specified capability to the process. This method grants the specified capability to the process or throws an error if it can not be granted. - Parameters: - capability: The capability to be granted - Returns: an invalidatable `Grant` object that represents the granted capability.
static init(bundleIdentifier: (string) | null, onInterruption: (() => void)): Promise<RenderingProcess>init(bundleIdentifier: String? = nil, onInterruption: @escaping () -> Void) async throwsAsynchronously finds an existing extension process or launches a one. This initializer launches a new rendering extension process. - Parameters: - `onInterruption` : A closure that is called if the helper process terminates.
makeLibXPCConnection(): SDKHandlefunc makeLibXPCConnection() throws -> xpc_connection_tCreates a new libXPC connection to the extension process. This method creates a connection to the extension process and returns it. - Returns: The connection object representing the created libXPC connection.
createVisibilityPropagationInteraction(): SDKHandlefunc createVisibilityPropagationInteraction() -> any UIInteractionattach the created interaction to a view to express that the content of that view is directly related to the working of this process. therefore, if the view is considered visible by the system then this process must also be considered to be visible. do not attempt to set an interaction on multiple views as interactions track their views - instead create a new interaction for each view that you want to propogate visibility to this process.
