Struct icu::pattern::MultiNamedPlaceholderKey

source ·
#[repr(transparent)]
pub struct MultiNamedPlaceholderKey<'a>(pub &'a str);
Expand description

A string wrapper for the MultiNamedPlaceholder pattern backend.

§Examples

use core::cmp::Ordering;
use core::str::FromStr;
use icu_pattern::MultiNamedPlaceholderKey;
use icu_pattern::MultiNamedPlaceholderPattern;
use icu_pattern::PatternItem;

// Parse the string syntax and check the resulting data store:
let pattern = MultiNamedPlaceholderPattern::try_from_str(
    "Hello, {person0} and {person1}!", Default::default()
)
.unwrap();

assert_eq!(
    pattern.iter().cmp(
        [
            PatternItem::Literal("Hello, "),
            PatternItem::Placeholder(MultiNamedPlaceholderKey(
                "person0".into()
            )),
            PatternItem::Literal(" and "),
            PatternItem::Placeholder(MultiNamedPlaceholderKey(
                "person1".into()
            )),
            PatternItem::Literal("!")
        ]
        .into_iter()
    ),
    Ordering::Equal
);
