A tour of Go: Exercise: Readers

go_reader_ex.go

package main

import "code.google.com/p/go-tour/reader"


type MyReader struct{}

func (r MyReader) Read(bytes []byte) (int, error) {
	for i := range bytes {
		bytes[i] = 65
	}
	return len(bytes), nil
}
// TODO: Add a Read([]byte) (int, error) method to MyReader.

func main() {
	reader.Validate(MyReader{})
}

The description of the problem didn't make sense to me. Thank you for the solution.

You are welcome

This is much nicer than what I had. I just stubbed in the following and was surprised when it actually passed lol!

func (r MyReader) Read(b []byte) (int, error) {
	b[0] = 'A'
	return 1, nil
}
