Struct spinoso_math::NotImplementedError

pub struct NotImplementedError(_);

Error that indicates a Math module function is not implemented.

Some math functions are not available in the Rust core library and require this crate to be built with extra compile-time features to enable additional dependencies.

Not implemented errors have an associated message.

This error corresponds to the Ruby NotImplementedError Exception class.

Examples

let err = NotImplementedError::new();
assert_eq!(err.message(), "NotImplementedError");

let err = NotImplementedError::with_message(
    "Artichoke was not built with Math::erf support"
);
assert_eq!(err.message(), "Artichoke was not built with Math::erf support");

Implementations

impl NotImplementedError

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

Construct a new, default not implemented error.

Examples

const ERR: NotImplementedError = NotImplementedError::new();
assert_eq!(ERR.message(), "NotImplementedError");

#[must_use]pub const fn with_message(message: &'static str) -> Self

Construct a new, not implemented error with a message.

Examples

const ERR: NotImplementedError = NotImplementedError::with_message(
    "Artichoke was not built with Math::erf support"
);
assert_eq!(ERR.message(), "Artichoke was not built with Math::erf support");

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

Retrieve the exception message associated with this not implemented error.

Examples

let err = NotImplementedError::new();
assert_eq!(err.message(), "NotImplementedError");

let err = NotImplementedError::with_message(
    "Artichoke was not built with Math::erf support"
);
assert_eq!(err.message(), "Artichoke was not built with Math::erf support");
