Type Alias Error 

pub type Error = Box<dyn Error + Send + Sync>;

The crate’s general-purpose error: any boxed, thread-safe std::error::Error.

Fallible store operations such as append and remove return Result<_, Error>. Use NotFound::is_not_found or has_not_found_io_error to test for the not-found case.
