Enum crosvm::crosvm::plugin::PluginObject

enum PluginObject {
    IoEvent {
        evt: Event,
        addr: IoeventAddress,
        length: u32,
        datamatch: u64,
    },
    Memory {
        slot: u32,
        length: usize,
    },
    IrqEvent {
        irq_id: u32,
        evt: Event,
    },
}

Each PluginObject represents one object that was instantiated by the guest using the Create request.

Each such object has an ID associated with it that exists in an ID space shared by every variant of PluginObject. This allows all the objects to be indexed in a single map, and allows for a common destroy method.

In addition to the destory method, each object may have methods specific to its variant type. These variant methods must be done by matching the variant to the expected type for that method. For example, getting the dirty log from a Memory object starting with an ID:

match objects.get(&request_id) {
   Some(&PluginObject::Memory { slot, length }) => vm.get_dirty_log(slot, &mut dirty_log[..]),
   _ => return Err(SysError::new(ENOENT)),
}
