Struct BaseRegistry 

pub struct BaseRegistry<const STRICT: bool>(/* private fields */);

A VMO handler registry that retrieves registered handlers by VMO KOID.

If STRICT is true, creating a handler for an unregistered VMO panics. Otherwise, it falls back to Passthrough.

Use BaseRegistry::register_handler or ScopedRegistry::register_handler to register RegistryHandler implementations that can be retrieved at-a-distance based on the VMO KOID.

Use this handler implementation in testing situations where the MMIO VMO might come over FIDL from an injected dependency. Register the VMO in a Registry before returning the VMO in an injected dependency fake.

Implementations

impl<const STRICT: bool> BaseRegistry<STRICT>

pub fn register_handler<H: RegistryHandler>(vmo: &Vmo, handler: H)

Registers handler for vmo.

The handler is installed in the global registry and never removed. See ScopedRegistry for alternatives.

pub fn register_shared_handler(vmo: &Vmo, handler: Arc<dyn RegistryHandler>)

Registers a shared reference-counted handler for vmo.

The handler is installed in the global registry and never removed. See ScopedRegistry for alternatives.

pub fn clear()

Clears all the registered VMOs.
