Functions

func Open 

func Open(connURL string) (drivers.Driver, error)

func WithInstance 

func WithInstance(dbInstance *sql.DB, config *Config) (drivers.Driver, error)

Types

type Config 

type Config struct {
	drivers.Config
	// contains filtered or unexported fields
}

type Mutex 

type Mutex struct {
	// contains filtered or unexported fields
}

Mutex is similar to sync.Mutex, except usable by morph to lock the db.

Pick a unique name for each mutex your plugin requires.

A Mutex must not be copied after first use.

func NewMutex 

func NewMutex(key string, driver drivers.Driver) (*Mutex, error)

NewMutex creates a mutex with the given key name.

returns error if key is empty.

func (*Mutex) Lock 

func (m *Mutex) Lock()

Lock locks m. If the mutex is already locked by any other morph instance, including the current one, the calling goroutine blocks until the mutex can be locked.

func (*Mutex) LockWithContext 

func (m *Mutex) LockWithContext(ctx context.Context) error

LockWithContext locks m unless the context is canceled. If the mutex is already locked by any other instance, including the current one, the calling goroutine blocks until the mutex can be locked, or the context is canceled.

The mutex is locked only if a nil error is returned.

func (*Mutex) Unlock 

func (m *Mutex) Unlock()

Unlock unlocks m. It is a run-time error if m is not locked on entry to Unlock.

Just like sync.Mutex, a locked Lock is not associated with a particular goroutine or a process.
