Struct MultiNamedPlaceholderKey

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

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
);

Trait Implementations

impl<'a> Clone for MultiNamedPlaceholderKey<'a>

fn clone(&self) -> MultiNamedPlaceholderKey<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for MultiNamedPlaceholderKey<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Ord for MultiNamedPlaceholderKey<'a>

fn cmp(&self, other: &MultiNamedPlaceholderKey<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for MultiNamedPlaceholderKey<'a>

fn eq(&self, other: &MultiNamedPlaceholderKey<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialOrd for MultiNamedPlaceholderKey<'a>

fn partial_cmp(&self, other: &MultiNamedPlaceholderKey<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'k, K, W> PlaceholderValueProvider<MultiNamedPlaceholderKey<'k>> for BTreeMap<K, W>

where K: Ord + Borrow<str>, W: Writeable,

type Error = MissingNamedPlaceholderError<'k>

type W<'a> = Result<&'a W, <BTreeMap<K, W> as PlaceholderValueProvider<MultiNamedPlaceholderKey<'k>>>::Error> where Self: 'a

The type of TryWriteable returned by Self::value_for.

type L<'a, 'l> = &'l str where Self: 'a

The type of Writeable returned by Self::map_literal.

fn value_for<'a>(&'a self, key: MultiNamedPlaceholderKey<'k>) -> Self::W<'a>

Returns the TryWriteable to substitute for the given placeholder.

fn map_literal<'a, 'l>(&'a self, literal: &'l str) -> Self::L<'a, 'l>

Maps a literal string to a Writeable that could contain parts.
