Expand description
This alias data is used for locale canonicalization. Each field defines a
mapping from an old identifier to a new identifier, based upon the rules in
from http://unicode.org/reports/tr35/#LocaleId_Canonicalization. The data
is stored in sorted order, allowing for binary search to identify rules to
apply. It is broken down into smaller vectors based upon some characteristic
of the data, to help avoid unnecessary searches. For example, the sgn_region
field contains aliases for sign language and region, so that it is not
necessary to search the data unless the input is a sign language.
The algorithm in tr35 is not guaranteed to terminate on data other than what is currently in CLDR. For this reason, it is not a good idea to attempt to add or modify aliases for use in this structure.
Fields
language_variants: VarZeroVec<'data, StrStrPairVarULE>
[language(-variant)+\] -> [langid]
This is not a map as it’s searched linearly according to the canonicalization rules.
sgn_region: ZeroMap<'data, TinyAsciiStr<3>, Language>
sgn-[region] -> [language]
language_len2: ZeroMap<'data, TinyAsciiStr<2>, str>
[language{2}] -> [langid]
language_len3: ZeroMap<'data, TinyAsciiStr<3>, str>
[language{3}] -> [langid]
language: VarZeroVec<'data, StrStrPairVarULE>
[langid] -> [langid]
This is not a map as it’s searched linearly according to the canonicalization rules.
script: ZeroMap<'data, TinyAsciiStr<4>, Script>
[script] -> [script]
region_alpha: ZeroMap<'data, TinyAsciiStr<2>, Region>
[region{2}] -> [region]
region_num: ZeroMap<'data, TinyAsciiStr<3>, Region>
[region{3}] -> [region]
complex_region: ZeroMap<'data, TinyAsciiStr<3>, ZeroSlice<Region>>
[region] -> [region]+
variant: ZeroMap<'data, TinyAsciiStr<8>, Variant>
[variant] -> [variant]
subdivision: ZeroMap<'data, TinyAsciiStr<7>, TinyAsciiStr<7>>
[value{7}] -> [value{7}]
