Functions

func NewMultiWriteCloser

func NewMultiWriteCloser(writeClosers ...io.WriteCloser) io.WriteCloser

NewMultiWriteCloser creates a new io.WriteCloser that duplicates its writes to all the provided writers.

func ReadString

func ReadString(r io.Reader) (string, error)

ReadString reads from the given reader and returns the content as a string.

func ToReadCloser

func ToReadCloser(r io.Reader) io.ReadCloser

ToReadCloser creates an io.ReadCloser from the given io.Reader. If it's not already, one will be created with a Close method that does nothing.

func ToWriteCloser

func ToWriteCloser(w io.Writer) io.WriteCloser

ToWriteCloser creates an io.WriteCloser from the given io.Writer. If it's not already, one will be created with a Close method that does nothing.

Types

type FlexiWriter

type FlexiWriter interface {
	io.Writer
	io.ByteWriter
	WriteString(s string) (int, error)
	WriteRune(r rune) (int, error)
}

As implemented by strings.Builder.

type HasBytesWriter

type HasBytesWriter struct {
	Match   bool
	Pattern []byte
	// contains filtered or unexported fields
}

HasBytesWriter is a writer that will set Match to true if the given pattern is found in the stream.

func (*HasBytesWriter) Write

func (h *HasBytesWriter) Write(p []byte) (n int, err error)

type OpenReadSeekCloser

type OpenReadSeekCloser func() (ReadSeekCloser, error)

OpenReadSeekCloser allows setting some other way (than reading from a filesystem) to open or create a ReadSeekCloser.

type ReadSeekCloser

type ReadSeekCloser interface {
	ReadSeeker
	io.Closer
}

ReadSeekCloser is implemented by afero.File. We use this as the common type for content in Resource objects, even for strings.

type ReadSeekCloserProvider

type ReadSeekCloserProvider interface {
	ReadSeekCloser() (ReadSeekCloser, error)
}

ReadSeekCloserProvider provides a ReadSeekCloser.

type ReadSeeker

type ReadSeeker interface {
	io.Reader
	io.Seeker
}

ReadSeeker wraps io.Reader and io.Seeker.

type ReadSeekerNoOpCloser

type ReadSeekerNoOpCloser struct {
	ReadSeeker
}

ReadSeekerNoOpCloser implements ReadSeekCloser by doing nothing in Close. TODO(bep) rename this and similar to ReadSeekerNopCloser, naming used in stdlib, which kind of makes sense.

func NewReadSeekerNoOpCloserFromBytes

func NewReadSeekerNoOpCloserFromBytes(content []byte) ReadSeekerNoOpCloser

NewReadSeekerNoOpCloserFromBytes uses strings.NewReader to create a new ReadSeekerNoOpCloser from the given bytes slice.

func NewReadSeekerNoOpCloserFromString

func NewReadSeekerNoOpCloserFromString(content string) ReadSeekerNoOpCloser

NewReadSeekerNoOpCloserFromString uses strings.NewReader to create a new ReadSeekerNoOpCloser from the given string.

func (ReadSeekerNoOpCloser) Close

func (r ReadSeekerNoOpCloser) Close() error

Close does nothing.

type StringReader

type StringReader interface {
	ReadString() string
}

StringReader provides a way to read a string.
