Struct LikelySubtagsForLanguage

pub struct LikelySubtagsForLanguage<'data> {
    pub language_script: ZeroMap<'data, (UnvalidatedTinyAsciiStr<3>, UnvalidatedTinyAsciiStr<4>), Region>,
    pub language_region: ZeroMap<'data, (UnvalidatedTinyAsciiStr<3>, UnvalidatedTinyAsciiStr<3>), Script>,
    pub language: ZeroMap<'data, UnvalidatedTinyAsciiStr<3>, (Script, Region)>,
    pub und: (Language, Script, Region),
}

This likely subtags data is used for the minimize and maximize operations.

Each field defines a mapping from an old identifier to a new identifier, based upon the rules in https://www.unicode.org/reports/tr35/#Likely_Subtags.

The data is stored is broken down into smaller vectors based upon the rules defined for the likely subtags maximize algorithm.

For efficiency, only the relevant part of the LanguageIdentifier is stored for searching and replacing. E.g., the language_script field is used to store rules for LanguageIdentifiers that contain a language and a script, but not a region.

This struct contains mappings when the input contains a language subtag. Also see LikelySubtagsForScriptRegion.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.

Fields

language_script: ZeroMap<'data, (UnvalidatedTinyAsciiStr<3>, UnvalidatedTinyAsciiStr<4>), Region>

Language and script.

language_region: ZeroMap<'data, (UnvalidatedTinyAsciiStr<3>, UnvalidatedTinyAsciiStr<3>), Script>

Language and region.

language: ZeroMap<'data, UnvalidatedTinyAsciiStr<3>, (Script, Region)>

Just language.

und: (Language, Script, Region)

Undefined.

Trait Implementations

impl<'data> Clone for LikelySubtagsForLanguage<'data>

fn clone(&self) -> LikelySubtagsForLanguage<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for LikelySubtagsForLanguage<'data>

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

Formats the value using the given formatter.

impl<'de: 'data, 'data> Deserialize<'de> for LikelySubtagsForLanguage<'data>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MaybeAsVarULE for LikelySubtagsForLanguage<'_>

type EncodedStruct = [()]

The VarULE type for this data struct, or [()] if it cannot be represented as VarULE.

impl<'data> PartialEq for LikelySubtagsForLanguage<'data>

fn eq(&self, other: &LikelySubtagsForLanguage<'data>) -> 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<'a> Yokeable<'a> for LikelySubtagsForLanguage<'static>

type Output = LikelySubtagsForLanguage<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

impl<'zf, 'zf_inner> ZeroFrom<'zf, LikelySubtagsForLanguage<'zf_inner>> for LikelySubtagsForLanguage<'zf>

fn zero_from(this: &'zf LikelySubtagsForLanguage<'zf_inner>) -> Self

Clone the other C into a struct that may retain references into C.
