Struct DetailOnly 

pub struct DetailOnly<Detail>(/* private fields */);

An ErrorSource that only provides error details but do not provide any trace. This can typically comes from primitive error types that do not implement Error. The Detail type is the error and the returned trace is None.

It is also possible to omit specifying the error as an error source, and instead place it as a field in the error variant. However specifying it as a DetailOnly source may give stronger hint to the reader that the particular error variant is caused by other underlying errors.
