Enum icu_pattern::ParserError

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

An error returned when parsing a pattern.

Examples

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

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

Type parameters

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

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> Debug for ParserError<E> where
    E: Debug, 

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

Formats the value using the given formatter.

impl<E> Display for ParserError<E> where
    E: Debug, 

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

Formats the value using the given formatter.

impl<E> Error for ParserError<E> where
    E: Debug, 

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<E: PartialEq> PartialEq<ParserError<E>> for ParserError<E> where
    E: Debug, 

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ParserError<E>) -> bool

This method tests for !=.
