Enum ExternalIdentifiers 

#[repr(u32)]
pub enum ExternalIdentifiers {
    SerialNumber = 0,
    Anonymous = 1,
}

When set, the system will prefer to present generic, fixed identifiers when challenged by external systems. The canonical use case for this is the serial number field in the USB device descriptor: normally, ExternalIdentifiers is 0, which means the device will present a semi-unique serial number (this is useful for users who plug in multiple devices and want to tell them apart). However, privacy-conscious users who don’t need or want to tell devices apart can increment this OWC and then the USB serial number will be replaced with a fixed pattern that is common across all devices.

Variants

SerialNumber = 0

Anonymous = 1

Trait Implementations

impl Clone for ExternalIdentifiers

fn clone(&self) -> ExternalIdentifiers

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExternalIdentifiers

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl OneWayEncoding for ExternalIdentifiers

const OFFSET: usize = 90

impl PartialEq for ExternalIdentifiers

fn eq(&self, other: &ExternalIdentifiers) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u32> for ExternalIdentifiers

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: u32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ExternalIdentifiers
