Functions

func IsReader

func IsReader(i any) bool

func ReadAllOrError

func ReadAllOrError(r io.Reader) []byte

ReadAllOrError will successfully return the data or return the error in the value return value. This is useful to simply test scripts where the data is printed for debugging or testing.

func ReadLimit

func ReadLimit(r io.Reader, limit uint) ([]byte, error)

ReadLimit returns the first `limit` bytes from a reader.

func ReaderToReadSeeker

func ReaderToReadSeeker(r io.Reader) (io.ReadSeeker, error)

ReaderToReadSeeker converts an `io.Reader` to an `io.ReadSeeker`. It does this by reading all data in `io.Reader`.

func Write

func Write(w *bufio.Writer, r io.Reader) error

Write writes from `Writer` to a `Reader`. See `osutil.WriteFileReader()`.

Types

type AtReader

type AtReader interface {
	io.Reader
	io.ReaderAt
}

type SkipWriter

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

SkipWriter is an `io.Writer` that skips writing the first `n` bytes passed. This is useful when the `io.Writer` writes some undesirable data which will be omitted with this functionality.

func NewSkipWriter

func NewSkipWriter(w io.Writer, off int) *SkipWriter

NewSkipWriter returns an SkipWriter that writes to w skipping the first offset off bytes.

func (*SkipWriter) Write

func (s *SkipWriter) Write(p []byte) (n int, err error)

Write fulfills the `io.Writer` interface.
