Tour of Go 2.0

Exercise: Readers

Implement a Reader type that produces an infinite stream of the ASCII character 'A'.

Add a Read([]byte) (int, error) method to MyReader. Fill every byte in the slice with 'A' and return the length — never return io.EOF.

main.go ▶ Run in Playground 
package main

import "golang.org/x/tour/reader"

type MyReader struct{}

// TODO: Add a Read([]byte) (int, error) method to MyReader.

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