Function table for a single plug-in controller type.

Slots are nullable at the ABI type level so the host can reject malformed manifests with null callbacks before constructing a controller. Generated vtables fill every required slot.

Fields

prepare: Option<unsafe extern "C" fn(request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>>

Prepares a controller request before the host registers runtime state.

create: Option<unsafe extern "C" fn(host: *const ControllerHostVTable, ctx: *const ControllerHostContext, config_json: BorrowedStr<'_>) -> *mut PluginControllerHandle>

Constructs a fresh controller instance bound to the supplied host vtable and instance context.

drop_handle: Option<unsafe extern "C" fn(handle: *mut PluginControllerHandle)>

Drops the controller instance and releases all of its resources.

type_name: Option<unsafe extern "C" fn() -> BorrowedStr<'static>>

Returns the canonical type name for this controller.

on_start: Option<unsafe extern "C" fn(handle: *mut PluginControllerHandle) -> PluginResult<()>>

on_stop: Option<unsafe extern "C" fn(handle: *mut PluginControllerHandle) -> PluginResult<()>>

on_resume: Option<unsafe extern "C" fn(handle: *mut PluginControllerHandle) -> PluginResult<()>>

on_reset: Option<unsafe extern "C" fn(handle: *mut PluginControllerHandle) -> PluginResult<()>>

on_dispose: Option<unsafe extern "C" fn(handle: *mut PluginControllerHandle) -> PluginResult<()>>

on_degrade: Option<unsafe extern "C" fn(handle: *mut PluginControllerHandle) -> PluginResult<()>>
