Struct artichoke::prelude::IndexError
source · pub struct IndexError { /* private fields */ }
Expand description
Ruby IndexError
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 IndexError
impl IndexError
sourcepub const fn new() -> IndexError
pub const fn new() -> IndexError
Construct a new, default IndexError
Ruby exception.
This constructor sets the exception message to IndexError
.
Examples
let exception = IndexError::new();
assert_eq!(exception.message(), b"IndexError");
sourcepub const fn with_message(message: &'static str) -> IndexError
pub const fn with_message(message: &'static str) -> IndexError
Construct a new, IndexError
Ruby exception with the given
message.
Examples
let exception = IndexError::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 = IndexError::new();
assert_eq!(exception.message(), b"IndexError");
let exception = IndexError::from("something went wrong");
assert_eq!(exception.message(), b"something went wrong");
