Functions

func Errorf

func Errorf(str string, args ...interface{}) error

Errorf is a variant of fmt.Errorf that returns an error being wrapped directly if it is one of a number of specific values, such as nil or io.EOF.

Types

type LimitedReader

type LimitedReader struct {
	R io.Reader
	N uint32
	E error
}

LimitedReader is a reimplementation of io.LimitedReader with two main differences:

* N is a uint32, allowing for larger sizes on 32-bit systems. * A custom error can be returned if N becomes zero.

func (*LimitedReader) Read

func (lr *LimitedReader) Read(buf []byte) (int, error)
