Struct icu::experimental::unicodeset_parse::ParseError

pub struct ParseError { /* private fields */ }

The error type returned by the parse functions in this crate.

See ParseError::fmt_with_source for pretty-printing and ParseErrorKind of the different types of errors represented by this struct.

Implementations

impl ParseError

pub fn fmt_with_source(&self, source: &str) -> impl Display

Pretty-prints this error and if applicable, shows where the error occurred in the source.

Must be called with the same source that was used to parse the set.

Examples

use icu::experimental::unicodeset_parse::*;

let source = "[[abc]-x]";
let set = parse(source);
assert!(set.is_err());
let err = set.unwrap_err();
assert_eq!(
    err.fmt_with_source(source).to_string(),
    "[[abc]-x← error: unexpected character 'x'"
);

use icu::experimental::unicodeset_parse::*;

let source = r"[\N{LATIN CAPITAL LETTER A}]";
let set = parse(source);
assert!(set.is_err());
let err = set.unwrap_err();
assert_eq!(
    err.fmt_with_source(source).to_string(),
    r"[\N← error: unimplemented"
);

pub fn kind(&self) -> ParseErrorKind

Returns the ParseErrorKind of this error.

pub fn offset(&self) -> Option<usize>

Returns the offset of this error in the source string, if it was specified.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl From<ParseErrorKind> for ParseError

fn from(kind: ParseErrorKind) -> ParseError

Converts to this type from the input type.

impl PartialEq for ParseError

fn eq(&self, other: &ParseError) -> 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.
