Struct BoxedError

pub struct BoxedError<ErrorKindT: Fail> { /* private fields */ }

An error type which stores the backtrace, cause pointer and error kind behind a Box.

The size of this object is always one pointer. It’s therefore smaller than UnboxedError, but requires an allocation when created.
