Struct spinoso_regexp::SyntaxError

pub struct SyntaxError(_);

Error that indicates a given Regexp pattern could not be parsed when given as a /.../ literal in Ruby source code.

This error is typically generated at parse-time.

This error corresponds to the Ruby SyntaxError Exception class.

Examples

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

let err = SyntaxError::with_message("premature end of char-class");
assert_eq!(err.message(), "premature end of char-class");

Implementations

impl SyntaxError

#[must_use]

pub const fn new() -> Self

Construct a new, default syntax error.

Examples

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

#[must_use]

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

Construct a new syntax error with a message.

Examples

const ERR: SyntaxError = SyntaxError::with_message("premature end of char-class");
assert_eq!(ERR.message(), "premature end of char-class");

#[must_use]

pub fn message(&self) -> &str

Retrieve the exception message associated with this syntax error.

Examples

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

let err = SyntaxError::with_message("premature end of char-class");
assert_eq!(err.message(), "premature end of char-class");
