Package vfs contains a driver that reads migrations from a virtual file system.

Package testing has the source tests.

List lists the registered drivers.

Open returns a new driver instance.

Parse returns Migration for matching Regex pattern.

Register globally registers a driver.

Regex matches the following pattern: 123_name.up.ext 123_name.down.ext.

Migration is a helper struct for source drivers that need to build the full directory tree in memory.

Migrations wraps Migration and has an internal index to keep track of Migration order.

Driver is the interface every source driver must implement.

Direction is either up or down.
