```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 -- https://bugs.ruby-lang.org/

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

This is desirable behaviour. The String with UTF-8 encoding cannot contain invalid byte sequences. If you want to store binary data, use `Encoding::BINARY` encoding.

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

A Binary string already presents the inspect output as a hex encoded String. As others have pointed out, if you want actual memory mapped binary buffers, use `IO::Buffer`. ---------------------------------------- Feature #20069: Buffer class in stdlib https://bugs.ruby-lang.org/issues/20069#change-105755 * 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 -- https://bugs.ruby-lang.org/
