    Types

    type CachingFetcher

    type CachingFetcher struct {
    	// contains filtered or unexported fields
    }

      A CachingFetcher is a blob.Fetcher and a blob.SeekFetcher.

      func NewCachingFetcher

      func NewCachingFetcher(cache blobserver.Cache, fetcher blob.Fetcher) *CachingFetcher

        NewCachingFetcher returns a CachingFetcher that fetches from fetcher and writes to and serves from cache.

        func (*CachingFetcher) Fetch

        func (cf *CachingFetcher) Fetch(br blob.Ref) (file io.ReadCloser, size uint32, err error)

        type DiskCache

        type DiskCache struct {
        	*CachingFetcher
        
        	// Root is the temp directory being used to store files.
        	// It is available mostly for debug printing.
        	Root string
        	// contains filtered or unexported fields
        }

          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

          func NewDiskCache(fetcher blob.Fetcher) (*DiskCache, error)

            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).

            func (*DiskCache) Clean

            func (dc *DiskCache) Clean()

              Clean cleans some or all of the DiskCache.
