Make Your Go Programs Use Less Memory.. Maybe — betteralign is a tool to detect structs that would use less memory if their fields were sorted and to then, optionally, sort such fields. It’s a fork of Go’s own fieldalignment tool that skips generated or test files, skips specially marked structs, doesn’t drop comments, and similar DX enhancements.
