Functions

func Get

func Get[T any](cache Cache, ctx context.Context, key string, callback func(ctx context.Context) (*T, error), options *Options) (*T, error)

Get gets value from the cache, load from callback function if cache value does not exist. Example:

  cache.Get(cacheInstance, ctx, "workspaces:uid", func(ctx context.Context) (*entities.Workspace, error) {
	   return db.Workspace.Get(ctx, workspaceId)
  }, nil)
