pub fn parse_steps(body: &str) -> Vec<(bool, String)>Expand description
Split a migration body on -- pylon:step markers into (transactional, sql) pairs, in order. A step is transactional unless its preceding
marker was -- pylon:step non-transactional (that marker applies to the
step it introduces, not the one it ends — matching the Python
implementation this replaces exactly, including the leading segment
before any marker always being transactional).
