Enum libgweather::LocationLevel

#[non_exhaustive]
pub enum LocationLevel {
    World,
    Region,
    Country,
    Adm1,
    City,
    WeatherStation,
    Detached,
    NamedTimezone,
}

The size/scope of a particular Location.

Locations form a hierarchy, with a GWEATHER_LOCATION_WORLD location at the top, divided into regions or countries, and so on.

Countries may or may not be divided into “adm1“s, and “adm1“s may or may not be divided into “adm2“s. A city will have at least one, and possibly several, weather stations inside it. Weather stations will never appear outside of cities.

Building a database with Location::world() will never create detached instances, but deserializing might.

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.

World

A location representing the entire world

Region

A location representing a continent or other top-level region

Country

A location representing a “country” (or other geographic unit that has an ISO-3166 country code)

Adm1

A location representing a “first-level administrative division”; ie, a state, province, or similar division

City

A location representing a city

WeatherStation

A location representing a weather station

Detached

A location that is detached from the database, for example because it was loaded from external storage and could not be fully recovered. The parent of this location is the nearest weather station

NamedTimezone

A location representing a named or special timezone in the world, such as UTC

Implementations

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

Formats the value using the given formatter.

impl Display for LocationLevel

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

Formats the value using the given formatter.

impl From<LocationLevel> for Value

fn from(v: LocationLevel) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for LocationLevel

type Checker = GenericValueTypeChecker<LocationLevel>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for LocationLevel

type ParamSpec = ParamSpecEnum

type SetValue = LocationLevel

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: LocationLevel) -> ParamSpecEnumBuilder<'_, LocationLevel>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for LocationLevel

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 LocationLevel

fn cmp(&self, other: &LocationLevel) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for LocationLevel

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

impl PartialOrd for LocationLevel

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

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

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

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

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

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

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

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

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

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

impl StaticType for LocationLevel

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for LocationLevel

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for LocationLevel

type Type = LocationLevel

Type to get the Type from.
