type DiskCache struct {
	*CachingFetcher

	// Root is the temp directory being used to store files.
	// It is available mostly for debug printing.

}

A DiskCache is a blob.Fetcher that serves from a local temp directory and is backed by a another blob.Fetcher (usually the pkg/client HTTP client).

func NewDiskCache

NewDiskCache returns a new DiskCache from a Fetcher, which is usually the pkg/client HTTP client (which typically has much higher latency and lower bandwidth than local disk).
