Struct artichoke::Error

pub struct Error(_);

The Error type, a wrapper around a dynamic exception type.

Error works a lot like Box<dyn std::error::Error>, but with these differences:

• Error requires that the error is 'static.
• Error requires that the error implement RubyException.
• Error can convert itself to a backtrace on the underlying Ruby VM.

All types that implement RubyException are able to be converted to Error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
