Struct icu_locid_transform::provider::expander::LikelySubtagsForScriptRegionV1

pub struct LikelySubtagsForScriptRegionV1<'data> {
    pub script_region: ZeroMap<'data, (UnvalidatedTinyAsciiStr<4>, UnvalidatedTinyAsciiStr<3>), Language>,
    pub script: ZeroMap<'data, UnvalidatedTinyAsciiStr<4>, (Language, Region)>,
    pub region: ZeroMap<'data, UnvalidatedTinyAsciiStr<3>, (Language, Script)>,
}

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 script_region field is used to store rules for LanguageIdentifiers that contain a script and a region, but not a language.

This struct contains mappings when the input does not contain a language subtag. Also see LikelySubtagsForLanguageV1.

🚧 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

script_region: ZeroMap<'data, (UnvalidatedTinyAsciiStr<4>, UnvalidatedTinyAsciiStr<3>), Language>

Script and region.

script: ZeroMap<'data, UnvalidatedTinyAsciiStr<4>, (Language, Region)>

Just script.

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

Just region.

Trait Implementations

impl<'data> Clone for LikelySubtagsForScriptRegionV1<'data>

fn clone(&self) -> LikelySubtagsForScriptRegionV1<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for LikelySubtagsForScriptRegionV1<'data>

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

Formats the value using the given formatter.

impl<'data> From<LikelySubtagsV1<'data>> for LikelySubtagsForScriptRegionV1<'data>

fn from(other: LikelySubtagsV1<'data>) -> Self

Converts to this type from the input type.

impl<'data> PartialEq for LikelySubtagsForScriptRegionV1<'data>

fn eq(&self, other: &LikelySubtagsForScriptRegionV1<'data>) -> 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<'a> Yokeable<'a> for LikelySubtagsForScriptRegionV1<'static>

type Output = LikelySubtagsForScriptRegionV1<'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, LikelySubtagsForScriptRegionV1<'zf_inner>> for LikelySubtagsForScriptRegionV1<'zf>

fn zero_from(this: &'zf LikelySubtagsForScriptRegionV1<'zf_inner>) -> Self

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