[][src]Struct artichoke::prelude::KeyError

pub struct KeyError { /* fields omitted */ }

Ruby KeyError 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 KeyError[src]

#[must_use]pub const fn new() -> KeyError[src]

Construct a new, default KeyError Ruby exception.

This constructor sets the exception message to KeyError.

Examples

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

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

Return the message this Ruby exception was constructed with.

Examples

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

#[must_use]pub const fn name(&self) -> &'static str[src]

Return this Ruby exception's class name.

Examples

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