Macro sql_migrations 

macro_rules! sql_migrations {
    (
        $(
            ($version:literal, $name:literal, $path:literal $(,)?)

}

Declares immutable migrations whose SQL bodies live in dedicated files.

Paths are resolved from the owning crate’s CARGO_MANIFEST_DIR. Keeping the ordered version and stable name explicit makes review and checksum drift behavior unchanged.
