Functions ¶
Types ¶
type Migrator ¶ added in v1.3.0
type Migrator struct {
Driver driver.Driver
// Path for schema migrations.
Path string
// // Path for storing executed migrations that are used for validation and for downgrading when the versions don't exist in MigrationsPath
// PrevPath string
// True if a transaction should be used for each file instead of per each major version
TxPerFile bool
// True if the migration should be interruptable
Interrupts bool
// Don't validate base upfiles
Force bool
// Schema to use
// Schema string
Schema string
}
