type LimitedReader ¶

type LimitedReader struct {
	R io.Reader // underlying reader
	N int64     // max bytes remaining
}

A LimitedReader reads from R but limits the amount of data returned to just N bytes. Each call to Read updates N to reflect the new amount remaining. Read returns EOF when N <= 0 or when the underlying R returns ErrLimitReached.

func LimitReader(r io.Reader, n int64) *LimitedReader

func (l *LimitedReader) Read(p []byte) (n int, err error)
