Types

type MySQLBackend

type MySQLBackend struct {
	sync.Mutex
	*sqlx.DB
	DatabaseURL       string
	QueryLimit        int
	QueryIDsLimit     int
	QueryAuthorsLimit int
	QueryKindsLimit   int
	QueryTagsLimit    int
}

func (*MySQLBackend) Close

func (b *MySQLBackend) Close()

func (*MySQLBackend) CountEvents

func (b *MySQLBackend) CountEvents(ctx context.Context, filter nostr.Filter) (int64, error)

func (*MySQLBackend) CountEventsFilters

func (b *MySQLBackend) CountEventsFilters(ctx context.Context, filters nostr.Filters) (int64, error)

CountEventsFilters counts the events matching any of the filters, counting an event that matches more than one of them only once. NIP-45 OR's the filters together into a single count, so summing a per-filter count would report overlapping filters more than once. The union is evaluated by the database: pulling the ids back to deduplicate them here would cost one id per stored event.

func (*MySQLBackend) DeleteEvent

func (b *MySQLBackend) DeleteEvent(ctx context.Context, evt *nostr.Event) error

func (*MySQLBackend) Init

func (b *MySQLBackend) Init() error

func (*MySQLBackend) QueryEvents

func (b *MySQLBackend) QueryEvents(ctx context.Context, filter nostr.Filter) (ch chan *nostr.Event, err error)

func (*MySQLBackend) ReplaceEvent

func (b *MySQLBackend) ReplaceEvent(ctx context.Context, evt *nostr.Event) error

func (*MySQLBackend) SaveEvent

func (b *MySQLBackend) SaveEvent(ctx context.Context, evt *nostr.Event) error
