type BatchFunc ¶

type BatchFunc[K comparable, V any] func([]context.Context, []K) map[K]Result[V]

BatchFunc is a function, which when given a slice of keys (string), returns a map of `results` indexed by keys.

The keys passed to this function are guaranteed to be unique.

type Loader ¶

type Loader[K comparable, V any] struct {
	// contains filtered or unexported fields
}

Loader implements the dataloader.Interface.

func NewBatchedLoader[K comparable, V any](batchFn BatchFunc[K, V], opts Options) *Loader[K, V]

func (l *Loader[K, V]) Load(ctx context.Context, key K) (value V, err error)

type Options ¶

type Options struct {
	Wait         time.Duration
	MaxThreshold uint
}

type Result ¶

type Result[V any] struct {
	Data  V
	Error error
}

Result is the data structure that a BatchFunc returns. It contains the resolved data, and any errors that may have occurred while fetching the data.
