Struct DeviceManager 

pub struct DeviceManager {
    devices: BTreeMap<Unsigned6Bit, AttachedUnit>,
    poll_queue: PollQueue,
    changes: ChangeIndex<Unsigned6Bit>,
}

Manages a collection of devices. Does not actually correspond to a tangible physical component of the TX-2 system.

Fields

devices: BTreeMap<Unsigned6Bit, AttachedUnit>

poll_queue: PollQueue

changes: ChangeIndex<Unsigned6Bit>
