Struct Registry 

pub struct Registry { /* private fields */ }

Registry of migrations, ordered by to_version then registration order.

Implementations

impl Registry

pub fn empty() -> Self

pub fn builtin() -> Self

Registry pre-loaded with every migration shipped by this crate.

pub fn register(&mut self, m: Box<dyn Migration>)

pub fn plan<'a>( &'a self, current: &Version, target: &Version, ) -> Vec<&'a dyn Migration>

Migrations whose to_version is > current and <= target and whose from_version requirement matches current.

pub fn run( &self, repo: &Repository, ref_name: &str, target: &Version, mode: RunMode, ) -> Result<Report, MigrateError>

Execute the plan.

Each migration runs as its own commit. On failure, earlier commits remain durable — operators re-run or branch from the last good commit.

pub fn iter(&self) -> impl Iterator<Item = &dyn Migration>
