Struct DeviceFacts 

pub struct DeviceFacts {
    pub serial: Option<String>,
    pub vendor_id: u16,
    pub product_id: u16,
    pub location_id: u64,
    pub manufacturer: Option<String>,
    pub product: Option<String>,
    pub speed: Option<String>,
    pub match_reason: Option<String>,
    pub label: String,
}

Everything the USB watch reported about one device, as reported.

The fields are what key is derived from plus the strings that let a person recognize the device in a scrolling log. Default is there so tests can state only the fields they care about.

Fields

serial: Option<String>

Serial number, exactly as reported (untrimmed).

vendor_id: u16

USB vendor ID.

product_id: u16

USB product ID.

location_id: u64

USB topology position: which port the device is in.

manufacturer: Option<String>

Manufacturer string from the USB descriptor.

product: Option<String>

Product string from the USB descriptor.

speed: Option<String>

Negotiated USB link speed, when the OS reports one.

match_reason: Option<String>

Why mtp-rs classified this device as MTP. Arrivals only, in practice.

label: String

What the daemon calls the device in its log (MtpDeviceInfo::display()).

Implementations

impl DeviceFacts

pub fn key(&self) -> String

The mount key: directory name and device identity in one.

This is the value the whole dry run is about. See device_dir_name for the serial-then-USB-address rule.

pub fn ident(&self) -> DeviceIdent

What the supervisor would be handed for this device.

The daemon’s real path goes through here too (crate::daemon::usb::ident_of is this function over an MtpDeviceInfo), so a dry run and a live mount can’t derive keys differently.

Trait Implementations
