// Package ioutil contains various constructs for io operations
package ioutil
// An function alias type that implements io.Writer
type WriterFunc func([]byte) (int, error)
// Delegates the call to the WriterFunc while implementing io.Writer
func (w WriterFunc) Write(b []byte) (int, error) {
return w(b)
}
// An function alias type that implements io.Reader
type ReaderFunc func([]byte) (int, error)
// Delegates the call to the WriterFunc while implementing io.Reader
func (r ReaderFunc) Read(b []byte) (int, error) {
return r(b)
}

Added src/0dev.org/ioutil/ioutil_test.go version [e21bc31120].
