Required Associated Types§

type Handler: Migrationhandler<NK, EK, Self, NewVersion>

Provided Methods§

source

fn migrate( g: TypedGraph<NK, EK, Self>, handler: &Self::Handler, new_schema: NewVersion ) -> GenericTypedResult<TypedGraph<NK, EK, NewVersion>, NK, EK>

mirgate the data store in one schema to another

Most of the time the default implementation is used as it uses an InBetween representation of the shemas to ensure type safety all throughout the migration process
