Struct artichoke_backend::extn::core::regexp::RegexpError

pub struct RegexpError(_);

Error that indicates a Regexp was malformed at runtime.

This error is typically generated by Regexp::compile.

This error corresponds to the Ruby RegexpError Exception class.

Examples

let err = RegexpError::new();
assert_eq!(err.message(), "RegexpError");

let err = RegexpError::with_message(r"invalid multibyte character: /\xFF\xFE/");
assert_eq!(err.message(), r"invalid multibyte character: /\xFF\xFE/");

Implementations

impl RegexpError

pub const fn new() -> RegexpError

Construct a new, default regexp error.

Examples

const ERR: RegexpError = RegexpError::new();
assert_eq!(ERR.message(), "RegexpError");

pub const fn with_message(message: &'static str) -> RegexpError

Construct a new regexp error with a message.

Examples

const ERR: RegexpError = RegexpError::with_message(r"invalid multibyte character: /\xFF\xFE/");
assert_eq!(ERR.message(), r"invalid multibyte character: /\xFF\xFE/");

pub fn message(&self) -> &str

Retrieve the exception message associated with this regexp error.

Examples

let err = RegexpError::new();
assert_eq!(err.message(), "RegexpError");

let err = RegexpError::with_message(r"invalid multibyte character: /\xFF\xFE/");
assert_eq!(err.message(), r"invalid multibyte character: /\xFF\xFE/");
