• type ReaderAndCloser

Functions ¶

func NewLimitedBufferReader ¶

func NewLimitedBufferReader(r io.Reader, n int) io.Reader

NewLimitedBufferReader returns a reader that reads from the given reader but limits the amount of data returned to at most n bytes.

func WriteAndSyncFile ¶

func WriteAndSyncFile(filename string, data []byte, perm os.FileMode) error

WriteAndSyncFile behaves just like ioutil.WriteFile in the standard library, but calls Sync before closing the file. WriteAndSyncFile guarantees the data is synced if there is no error returned.

Types ¶

type ReaderAndCloser ¶

type ReaderAndCloser struct {
	io.Reader
	io.Closer
}

ReaderAndCloser implements io.ReadCloser interface by combining reader and closer together.
