Trait avocado::error::ErrorExt

pub trait ErrorExt: Error {
    fn as_std_error(&self) -> &dyn Error;

    fn reason(&self) -> Option<&dyn ErrorExt> { ... }
    fn backtrace(&self) -> Option<&Backtrace> { ... }
}

Slightly augmented trait for backtrace-able errors.

Required Methods

fn as_std_error(&self) -> &dyn Error

Until subtrait coercions are implemented, this helper method should return the receiver as an &std::error::Error trait object.

Provided Methods

fn reason(&self) -> Option<&dyn ErrorExt>

Similar to std::error::Error::cause(), but with richer type info.

fn backtrace(&self) -> Option<&Backtrace>

Returns the deepest possible backtrace, if any.
