Types

type Reader

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

Reader uses bytes.Map to transform the input from an io.Reader to alter an inbound stream

func (*Reader) Close

func (f *Reader) Close() error

Close meets the io.Closer interface

func (*Reader) Read

func (f *Reader) Read(p []byte) (int, error)

Read checks for changes to the slice, then rewrites the slice if any are found

type RuneMap

type RuneMap func(r rune) rune

RuneMap drops unwanted runes by returning false. This

func XML10Filter

func XML10Filter(replacement rune) RuneMap
