Types

type TimedMemoize

type TimedMemoize[T any] struct {
	// contains filtered or unexported fields
}

TimedMemoize wraps a function returning (value, error) and caches the value AND the error for a specific time. This cache is mainly used to ensure external calls rates are reasonable. The cache is thread-safe.

func NewTimedMemoize

func NewTimedMemoize[T any](getter func(ctx context.Context) (T, error), duration time.Duration) *TimedMemoize[T]

NewTimedMemoize builds and returns a TimedMemoize

func (*TimedMemoize[T]) Get

func (c *TimedMemoize[T]) Get(ctx context.Context) (T, error)

Get does a cache lookup and updates the cache in case of cache miss.
