Trait intl_pluralrules::operands::IntoPluralOperands
source · pub trait IntoPluralOperands {
fn into_plural(self) -> Result<PluralOperands, &'static str>;
}Expand description
A trait that can be implemented on any type to allow it for passing to select. This trait is made public for implementations of custom types. If you are using generic types, you should use from.
Example
use intl_pluralrules::operands::*;
use intl_pluralrules::{IntlPluralRules, PluralRuleType, PluralCategory};
struct MyType {
value: isize
}
impl IntoPluralOperands for MyType {
fn into_plural(self) -> Result<PluralOperands, &'static str> {
Ok(PluralOperands {
n: self.value as f64,
i: self.value as isize,
v: 0,
w: 0,
f: 0,
t: 0,
})
}
}
let pr = IntlPluralRules::create("en", PluralRuleType::CARDINAL).unwrap();
let v = MyType { value: 5 };
assert_eq!(pr.select(v), Ok(PluralCategory::OTHER));
