Struct co2mon::Reading

pub struct Reading { /* fields omitted */ }

A reading consisting of temperature (in °C) and CO₂ concentration (in ppm) values.

Example

let sensor = Sensor::open_default()?;
let reading = sensor.read()?;
println!("{} °C, {} ppm CO₂", reading.temperature(), reading.co2());

Methods

impl Reading

pub fn temperature(&self) -> f32

Returns the measured temperature in °C.

Example

let sensor = Sensor::open_default()?;
let reading = sensor.read()?;
println!("{} °C", reading.temperature());

pub fn co2(&self) -> u16

Returns the CO₂ concentration in ppm (parts per million).

Example

let sensor = Sensor::open_default()?;
let reading = sensor.read()?;
println!("{} ppm CO₂", reading.co2());

Trait Implementations

impl Clone for Reading

fn clone(&self) -> Reading

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialOrd<Reading> for Reading

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl PartialEq<Reading> for Reading

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for Reading

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

Formats the value using the given formatter.

impl Serialize for Reading

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for Reading

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
