Enum ChainTail

Source 
pub enum ChainTail {
    Backtrace(Backtrace),
    Error(Error),
}
Expand description

Helper type which is either a Backtrace or an full failure::Error.

This can be used to either just contain a backtrace into an custom error or to chain it in front of another error without adding another backtrace, depending on the creating context.
