assert_eq!(err.message(), r"invalid multibyte character: /\xFF\xFE/");
Implementations
sourceimpl RegexpError
impl RegexpError
sourcepub const fn new() -> RegexpError
pub const fn new() -> RegexpError
Construct a new, default regexp error.
Examples
const ERR: RegexpError = RegexpError::new();
assert_eq!(ERR.message(), "RegexpError");
sourcepub const fn with_message(message: &'static str) -> 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/");
sourcepub fn message(&self) -> &str
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/");
