pub struct SyntaxError(/* private fields */);
Expand description
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§
Source§impl SyntaxError
impl SyntaxError
Sourcepub const fn new() -> Self
pub const fn new() -> Self
Construct a new, default syntax error.
§Examples
const ERR: SyntaxError = SyntaxError::new();
assert_eq!(ERR.message(), "SyntaxError");
Sourcepub const fn with_message(message: &'static str) -> Self
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");
Sourcepub fn message(&self) -> &str
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");
