Enum RegexError 

pub enum RegexError {
    Syntax {
        message: String,
        offset: usize,
    },
}

Error type for Perl regex validation failures.

Variants

Syntax

Syntax error at a specific byte offset in the regex pattern.

Fields

message: String

Human-readable description of the syntax issue.

offset: usize

Byte offset where the error was detected.

Implementations

impl RegexError

pub fn syntax(message: impl Into<String>, offset: usize) -> Self

Create a new syntax error with a message and byte offset.

Trait Implementations

impl Clone for RegexError

fn clone(&self) -> RegexError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegexError

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

Formats the value using the given formatter.

impl Display for RegexError

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

Formats the value using the given formatter.

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: &RegexError) -> 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.
