Methods for interactions with database

type Storage

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

func New

func New(storagePath string) (*Storage, error)

New - creates new database in the given storagePath with tables

func (*Storage) DeleteExpression

func (s *Storage) DeleteExpression(ctx context.Context, id int64) error

DeleteExpression - deletes expression row from database table

func (*Storage) InsertExpression

func (s *Storage) InsertExpression(ctx context.Context, expr *Expression) (int64, error)

InsertExpression - putting new expression into database table

func (*Storage) LoginUser

func (s *Storage) LoginUser(ctx context.Context, uname, pswrd string) (string, error)

LoginUser selects a user from database and generates new jwt token for him

func (*Storage) RegisterUser

func (s *Storage) RegisterUser(ctx context.Context, uname, pswrd string) error

RegisterUser inserts a new user into database when it registers

func (*Storage) SelectAllExpressions

func (s *Storage) SelectAllExpressions(ctx context.Context) ([]Expression, error)
