icu_plurals
icu_plurals
is one of the ICU4X
components.
This API provides functionality to determine the plural category appropriate for a given number in a given language.
For example in English language, when constructing a message
such as { num } items
, the user has to prepare
two variants of the message:
1 item
0 items
,2 items
,5 items
,0.5 items
etc.
The former variant is used when the placeholder variable has value 1
,
while the latter is used for all other values of the variable.
Unicode defines Language Plural Rules
as a mechanism to codify those
variants and provides data and algorithms to calculate
appropriate Plural Category
.
Examples
use langid;
use ;
let lid = langid!;
let provider = get_provider;
let pr = try_new
.expect;
assert_eq!;
