```ruby

class Bytes < String

  def inspect

    bytes.pack("c*").unpack1("H*")

  end

end



s = Bytes.new(SecureRandom.bytes(10))



```



What might be more interesting than suggesting an unnecessary class, but suggesting a different `#inspect` if the encoding is `ASCII-8BIT` or `BINARY` (because `SecureRandom.bytes(10).encoding # => #<Encoding:ASCII-8BIT>`, which will eventually be called `Encoding:BINARY`).I���m not sure what such inspect should be, because the inspect that I wrote above for `Bytes` is both inefficient and incorrect (because the representation is not what is shown on `#inspect`, which differs from other strings).



Maybe:



```ruby

class Bytes < String

  def inspect

    "#<#{encoding}:#{bytes.pack("c*").unpack1("H*")}>"

  end

end



Bytes.new(SecureRandom.bytes(10))

=> #<ASCII-8BIT:1c2dc1463d30c6ed0b9a>

```

Feature #20069: Buffer class in stdlib

https://bugs.ruby-lang.org/issues/20069#change-105707



* Author: pynix (Pynix wang)

* Status: Open

* Priority: Normal

----------------------------------------

ruby use `String` to deal with bytes, this cause error on irb  "invalid byte sequence in utf-8"



can we get a builtin class like Buffer or Bytes that represent as hex string
