Enum icu::pattern::SinglePlaceholderKey
source · pub enum SinglePlaceholderKey {
Singleton,
}
Expand description
A singleton enum for the SinglePlaceholder
pattern backend.
§Examples
use core::cmp::Ordering;
use core::str::FromStr;
use icu_pattern::PatternItem;
use icu_pattern::SinglePlaceholder;
use icu_pattern::SinglePlaceholderKey;
use icu_pattern::SinglePlaceholderPattern;
// Parse the string syntax and check the resulting data store:
let pattern = SinglePlaceholderPattern::try_from_str("Hello, {0}!", Default::default()).unwrap();
assert_eq!(
pattern.iter().cmp(
[
PatternItem::Literal("Hello, "),
PatternItem::Placeholder(SinglePlaceholderKey::Singleton),
PatternItem::Literal("!")
]
.into_iter()
),
Ordering::Equal
);
