- switch to ClientConnInterface - use command type alias for map of commands - add error return to command functions and handle in app.go - inline formatJSON function in getAllAssets.go - replace most panics with error returns - remove error wrapping in listen.go and further down the line - use strconv.ParseUint instead of ParseFloat - use WithCancelCause in transact.go to grab and propagate error from go routine - unmarshal and return []Asset in atb.GetAllAssets - switch to rand package - remove dependency to protobuf reflect package - switch to sync.OnceValues for caching parser - fixed typo in events sample connect.go Signed-off-by: Stanislav Jakuschevskij <stas@two-giants.com>
