Struct artichoke::prelude::NoMemoryError

pub struct NoMemoryError { /* private fields */ }

Ruby NoMemoryError 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 NoMemoryError

pub const fn new() -> NoMemoryError

Construct a new, default NoMemoryError Ruby exception.

This constructor sets the exception message to NoMemoryError.

Examples

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

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

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

Examples

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

Trait Implementations

impl Clone for NoMemoryError

fn clone(&self) -> NoMemoryError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NoMemoryError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl Ord for NoMemoryError

fn cmp(&self, other: &NoMemoryError) -> Ordering

This method returns an Ordering between self and other.

fn eq(&self, other: &NoMemoryError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.
