Struct Exception

pub struct Exception { /* private fields */ }

Exception. Most will come from the C API.

Implementations

impl Exception

pub fn what(&self) -> &str

The error message.

pub fn location(&self) -> &'static Location<'static>

The location of the error.

The location is obtained from std::panic::Location::caller() and points to the location in the code where the error was created and not where it was propagated.

pub fn custom(what: impl Into<String>) -> Self

Creates a new exception with the given message.
