Enum icu::pattern::ParserError

#[non_exhaustive]
pub enum ParserError<E>
where
    E: Debug,
{
    IllegalCharacter(char),
    InvalidPlaceholder(E),
    UnclosedPlaceholder,
    UnclosedQuotedLiteral,
}

An error returned when parsing a pattern.

✨ Enabled with the alloc Cargo feature.

Examples

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

let mut parser = Parser::<usize>::new("{0", ParserOptions::default());
assert_eq!(Err(ParserError::UnclosedPlaceholder), parser.try_next());

Type parameters

• E: An error of the replacement type which implements FromStr.

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.

IllegalCharacter(char)

Encountered an illegal character.

InvalidPlaceholder(E)

Placeholder hould not be parsed from the given string slice.

UnclosedPlaceholder

The pattern contains an unclosed placeholder.

UnclosedQuotedLiteral

The pattern contains an unclosed quoted literal.

Trait Implementations

impl<E> Debug for ParserError<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Display for ParserError<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Error for ParserError<E>

where E: Debug,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<E> PartialEq for ParserError<E>

where E: PartialEq + Debug,

fn eq(&self, other: &ParserError<E>) -> 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<E> StructuralPartialEq for ParserError<E>

where E: Debug,
