Enum Status 

#[non_exhaustive]
#[repr(u8)]
pub enum Status {
    Error = 0,
    Green = 1,
    Yellow = 2,
    Red = 3,
}

CO2 level status indicator.

This enum is marked #[non_exhaustive] to allow adding new status levels in future versions without breaking downstream code.

Ordering

Status values are ordered by severity: Error < Green < Yellow < Red. This allows threshold comparisons like if status >= Status::Yellow { warn!(...) }.

Display vs Serialization

Note: The Display trait returns human-readable labels (“Good”, “Moderate”, “High”), while serde serialization uses the variant names (“Green”, “Yellow”, “Red”).

use aranet_types::Status;

// Display is human-readable
assert_eq!(format!("{}", Status::Green), "Good");

// Ordering works for threshold comparisons
assert!(Status::Red > Status::Yellow);
assert!(Status::Yellow > Status::Green);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Error = 0

Error or invalid reading.

Green = 1

CO2 level is good (green).

Yellow = 2

CO2 level is moderate (yellow).

Red = 3

CO2 level is high (red).

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Status

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Status

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Status

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

Formats the value using the given formatter.

impl From<u8> for Status

fn from(value: u8) -> Status

Converts to this type from the input type.

impl Hash for Status

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Status

fn cmp(&self, other: &Status) -> 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 Status

fn eq(&self, other: &Status) -> 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.

fn partial_cmp(&self, other: &Status) -> 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.

impl Serialize for Status

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Status

impl Eq for Status

impl StructuralPartialEq for Status
