Struct sgp30::Humidity

pub struct Humidity { /* private fields */ }

Absolute humidity in g/m³.

Internally this is represented as a 8.8bit fixed-point number.

To construct a Humidity instance, either use the lossless new() constructor, or the lossy from_f32() method.

Implementations

impl Humidity

pub fn new(integer: u8, fractional: u8) -> Result<Self, HumidityError>

Create a new Humidity instance.

The humidity should be passed in as a 8.8bit fixed-point number.

Examples:

• The pair (0x00, 0x01) represents 1/256 g/m³ (0.00390625)
• The pair (0xFF, 0xFF) represents 255 g/m³ + 255/256 g/m³ (255.99609375)
• The pair (0x10, 0x80) represents 16 g/m³ + 128/256 g/m³ (16.5)

pub fn from_f32(val: f32) -> Result<Self, HumidityError>

Create a new Humidity instance from a f32.

When converting, the fractional part will always be rounded down.

pub fn as_bytes(&self) -> [u8; 2]

Convert this to the binary fixed-point representation expected by the SGP30 sensor.

Trait Implementations

impl Clone for Humidity

fn clone(&self) -> Humidity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Humidity

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

Formats the value using the given formatter.

impl From<Humidity> for f32

fn from(val: Humidity) -> Self

Convert a Humidity instance to a f32.

impl PartialEq for Humidity

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

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

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

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