infinite

Infinite provides an io.Reader that never returns EOF. Instead, a pattern is repeated forever.

I needed this for performance testing of a streaming JSON parser.

Usage

r := infinite.NewReader([]byte("Hello infinity!"))

buf := make([]byte, 16)

r.Read(buf)
fmt.Printf(string(buf) + "\n")

r.Read(buf)
fmt.Printf(string(buf) + "\n")

// Output:
// Hello infinity!H
// ello infinity!He

Limitations

The buffer size must be a multiple of sizeof(__uint128_t)!
