Struct RegexError 

pub struct RegexError {
    pub offset: usize,
    pub kind: RegexErrorKind,
}

Why a pattern is outside the accepted subset, and where.

offset is the byte offset in the pattern where the problem starts; it is always on a character boundary and never past the end of the pattern.

Examples

use textmate_lang::{RegexErrorKind, validate_regex};

let err = validate_regex("a(b|c").unwrap_err();
assert_eq!(err.offset, 1);
assert_eq!(err.kind, RegexErrorKind::UnclosedGroup);
assert_eq!(err.to_string(), "at byte 1: unclosed group: `(` has no matching `)`");

Fields

offset: usize

Byte offset of the problem in the pattern.

kind: RegexErrorKind

What the problem is.

impl Eq for RegexError

impl Error for RegexError

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 PartialEq for RegexError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
