Package migrate implements the migration of data from one type of Keeper to another.
var (
ErrNoStores = errors.New("no stores found in source keeper")
ErrDupKeys = errors.New(
"duplicate keys found in destination stores, enable skipping or clobbering of existing data to continue migration",
)
)
type ErrDuplicateKeys
type ErrDuplicateKeys struct {
// map[store][]keys
Duplicates map[string][][]byte
}
func NewDuplicateKeysErr
func NewDuplicateKeysErr(duplicates map[string][][]byte) *ErrDuplicateKeys
func (ErrDuplicateKeys) Error
func (e ErrDuplicateKeys) Error() string
func (ErrDuplicateKeys) Unwrap
func (e ErrDuplicateKeys) Unwrap() error
type Migrator
type Migrator struct {
From database.Keeper
To database.Keeper
}
func NewMigrator
func NewMigrator(from, to database.Keeper) (*Migrator, error)
func (*Migrator) CheckDupes
func (m *Migrator) CheckDupes() error
func (*Migrator) Migrate
func (m *Migrator) Migrate() error
func (*Migrator) WithClobber
func (m *Migrator) WithClobber() *Migrator
WithClobber sets the clobber flag on the Migrator, allowing it to overwrite existing data in the destination Keeper.
func (*Migrator) WithSkipExisting
func (m *Migrator) WithSkipExisting() *Migrator
