Enum DeviceIdentity 

pub enum DeviceIdentity {
    Serial(String),
    Unit([u8; 4]),
}

A device’s own identity, used to disambiguate two same-model direct devices.

Variants

Serial(String)

Case-folded serial number.

Unit([u8; 4])

Raw HID++ unit id, used when no serial is reported.

Implementations

impl DeviceIdentity

pub fn from_parts(serial: Option<&str>, unit_id: [u8; 4]) -> Self

Prefer the serial number (case-folded) when present, else the unit id.

Trait Implementations

impl Clone for DeviceIdentity

fn clone(&self) -> DeviceIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceIdentity

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

Formats the value using the given formatter.

impl Eq for DeviceIdentity

impl Ord for DeviceIdentity

fn cmp(&self, other: &DeviceIdentity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DeviceIdentity

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for DeviceIdentity

fn partial_cmp(&self, other: &DeviceIdentity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
