Enum icu::locale::fallback::LocaleFallbackPriority

#[non_exhaustive]
pub enum LocaleFallbackPriority {
    Language,
    Script,
    Region,
}

Hint for which subtag to prioritize during fallback.

For example, "en-US" might fall back to either "en" or "und-US" depending on this enum.

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.

Language

Prioritize the language. This is the default behavior.

For example, "en-US" should go to "en" and then "und".

Script

Prioritize the script.

For example, "en-US" should go to "en" and then "und-Latn" and then "und".

Region

Prioritize the region.

For example, "en-US" should go to "und-US" and then "und".

Implementations

impl LocaleFallbackPriority

pub const fn default() -> LocaleFallbackPriority

Const-friendly version of Default::default.

Trait Implementations

impl Clone for LocaleFallbackPriority

fn clone(&self) -> LocaleFallbackPriority

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LocaleFallbackPriority

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

Formats the value using the given formatter.

impl Default for LocaleFallbackPriority

fn default() -> LocaleFallbackPriority

Returns the “default value” for a type.

impl Ord for LocaleFallbackPriority

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

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

impl PartialOrd for LocaleFallbackPriority

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