pub struct SignalException { /* private fields */ }
Expand description
Ruby SignalException
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§
Source§impl SignalException
impl SignalException
Sourcepub const fn new() -> SignalException
pub const fn new() -> SignalException
Construct a new, default SignalException
Ruby exception.
This constructor sets the exception message to SignalException
.
§Examples
let exception = SignalException::new();
assert_eq!(exception.message(), b"SignalException");
Sourcepub const fn with_message(message: &'static str) -> SignalException
pub const fn with_message(message: &'static str) -> SignalException
Construct a new, SignalException
Ruby exception with the given
message.
§Examples
let exception = SignalException::with_message("an error occurred");
assert_eq!(exception.message(), b"an error occurred");
Sourcepub fn message(&self) -> &[u8] ⓘ
pub fn message(&self) -> &[u8] ⓘ
Return the message this Ruby exception was constructed with.
§Examples
let exception = SignalException::new();
assert_eq!(exception.message(), b"SignalException");
let exception = SignalException::from("something went wrong");
assert_eq!(exception.message(), b"something went wrong");
