Enum icu::pattern::ParsedPatternItem

#[non_exhaustive]
pub enum ParsedPatternItem<'s, P> {
    Placeholder(P),
    Literal {
        content: Cow<'s, str>,
        quoted: bool,
    },
}

A PatternItem with additional detail returned by the Parser.

✨ Enabled with the alloc Cargo feature.

Examples

use icu_pattern::{ParsedPatternItem, Parser, ParserOptions};

let input = "{0}, {1}";

let mut parser = Parser::new(input, ParserOptions::default());

let mut result = vec![];

while let Some(element) =
    parser.try_next().expect("Failed to advance iterator")
{
    result.push(element);
}

assert_eq!(
    result,
    &[
        ParsedPatternItem::Placeholder(0),
        ParsedPatternItem::Literal {
            content: ", ".into(),
            quoted: false
        },
        ParsedPatternItem::Placeholder(1),
    ]
);

Type parameters

• P: A placeholder type which implements FromStr.

Lifetimes

• s: The life time of an input string slice being parsed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Placeholder(P)

Literal

Fields

content: Cow<'s, str>

quoted: bool

Trait Implementations

impl<'s, P> Clone for ParsedPatternItem<'s, P>

where P: Clone,

fn clone(&self) -> ParsedPatternItem<'s, P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'s, P> Debug for ParsedPatternItem<'s, P>

where P: Debug,

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

Formats the value using the given formatter.

impl<'s, P> From<(&'s str, bool)> for ParsedPatternItem<'s, P>

fn from(input: (&'s str, bool)) -> ParsedPatternItem<'s, P>

Converts to this type from the input type.

impl<'a, K> From<ParsedPatternItem<'a, K>> for PatternItemCow<'a, K>

fn from(value: ParsedPatternItem<'a, K>) -> PatternItemCow<'a, K>

Converts to this type from the input type.

impl<'s, P> PartialEq for ParsedPatternItem<'s, P>

where P: PartialEq,

fn eq(&self, other: &ParsedPatternItem<'s, P>) -> 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.
