Functions

func Destroy

func Destroy(env *lmdb.Env)

Destroy closes env and removes its directory from the file system.

func NewEnv

func NewEnv(opt *EnvOptions) (env *lmdb.Env, err error)

NewEnv returns a test environment with the given options at a temporary path.

func OpenDBI

func OpenDBI(env *lmdb.Env, name string, flags uint) (lmdb.DBI, error)

OpenDBI is a helper that opens a transaction, opens the named database, commits the transaction, and returns the open DBI handle to the caller.

func OpenRoot

func OpenRoot(env *lmdb.Env, flags uint) (lmdb.DBI, error)

OpenRoot is a helper that opens a transaction, opens the root database, commits the transaction, and returns the open DBI handle to the caller.

func Put

func Put(env *lmdb.Env, dbi lmdb.DBI, items ItemList) error

Put writes items to the handle dbi in env.
