[cachebag]

implement zbus proxy traits for modemmanager interfaces.

interfaces to cover

manager (org.freedesktop.ModemManager1)

path: /org/freedesktop/ModemManager1

methods:

• ScanDevices()
• SetLogging(level: &str)
• InhibitDevice(uid: &str) -> u32

properties:

• Version: String

modem (org.freedesktop.ModemManager1.Modem)

methods:

• Enable(enable: bool)
• ListBearers() -> Vec<ObjectPath>
• CreateBearer(properties: Dict) -> ObjectPath
• DeleteBearer(bearer: ObjectPath)

modem.simple (org.freedesktop.ModemManager1.Modem.Simple)

methods:

• Connect(properties: Dict) -> ObjectPath
• Disconnect(bearer: ObjectPath)
• GetStatus() -> Dict

sim (org.freedesktop.ModemManager1.Sim)

methods:

• SendPin(pin: &str)
• SendPuk(puk: &str, pin: &str)

pattern

follow nmrs proxy style:

#[proxy(
    interface = "org.freedesktop.ModemManager1.Modem",
    default_service = "org.freedesktop.ModemManager1"
)]
pub trait MMModem {
    fn enable(&self, enable: bool) -> zbus::Result<()>;
    // ...
}

optional (defer if needed)

• Modem.Modem3gpp — 3gpp-specific registration, ussd
• Modem.Location — gps
• Modem.Signal — detailed signal info
• Sms, Messaging — sms send/receive
