* Add crate snafu * Replace all inline structs in AnkiError * Derive Snafu on AnkiError * Use snafu for card type errors * Use snafu whatever error for InvalidInput * Use snafu for NotFoundError and improve message * Use snafu for FileIoError to attach context Remove IoError. Add some context-attaching helpers to replace code returning bare io::Errors. * Add more context-attaching io helpers * Add message, context and backtrace to new snafus * Utilize error context and backtrace on frontend * Rename LocalizedError -> BackendError. * Remove DocumentedError. * Have all backend exceptions inherit BackendError. * Rename localized(_description) -> message * Remove accidentally committed experimental trait * invalid_input_context -> ok_or_invalid * ensure_valid_input! -> require! * Always return `Err` from `invalid_input!` Instead of a Result to unwrap, the macro accepts a source error now. * new_tempfile_in_parent -> new_tempfile_in_parent_of * ok_or_not_found -> or_not_found * ok_or_invalid -> or_invalid * Add crate convert_case * Use unqualified lowercase type name * Remove uses of snafu::ensure * Allow public construction of InvalidInputErrors (dae) Needed to port the AnkiDroid changes. * Make into_protobuf() public (dae) Also required for AnkiDroid. Not sure why it worked previously - possible bug in older Rust version?
