Struct spinoso_exception::SyntaxError

pub struct SyntaxError { /* fields omitted */ }

Ruby SyntaxError error type.

Descendants of class Exception are used to communicate between Kernel#raise and rescue statements in begin ... end blocks. Exception objects carry information about the exception – its type (the exception’s class name), an optional descriptive string, and optional traceback information. Exception subclasses may add additional information like NameError#name.

Implementations

impl SyntaxError

pub const fn new() -> Self

Construct a new, default SyntaxError Ruby exception.

This constructor sets the exception message to SyntaxError.

Examples

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

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

Construct a new, SyntaxError Ruby exception with the given message.

Examples

let exception = SyntaxError::with_message("an error occurred");
assert_eq!(exception.message(), b"an error occurred");

pub fn message(&self) -> &[u8]

Return the message this Ruby exception was constructed with.

Examples

let exception = SyntaxError::new();
assert_eq!(exception.message(), b"SyntaxError");
let exception = SyntaxError::from("something went wrong");
assert_eq!(exception.message(), b"something went wrong");

pub const fn name(&self) -> &'static str

Return this Ruby exception’s class name.

Examples

let exception = SyntaxError::new();
assert_eq!(exception.name(), "SyntaxError");
