Implementations

impl Counter

pub const fn new(label: &'static str) -> Counter

Create a new counter with the provided label.

pub fn click(&'static self)

Increment the counter by one.

pub fn count(&'static self, x: u64)

Increment the counter by x.

Trait Implementations

impl Sensor for Counter

type Reading = u64

The type of a sensor reading.

fn label(&'static self) -> &'static str

Every sensor has a label. This is a UTF-8 string. It must be static because sensors are meant to be instantiated statically as well, and having the constraint here enforces that.

fn read(&'static self) -> u64

Return a linearlizable view of the sensor.
