[−][src]Enum mail_headers::error::ChainTail

pub enum ChainTail {
    Backtrace(Backtrace),
    Error(FError),
}

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.

Variants

Error(FError)
