Feature #17834
Updated by dsisnero (Dominic Sisneros) over 3 years ago
"this is a string".bytes should == Bytes.new('this is a string') # an immutable bytes object that implements memory view
``` ruby
bytestring = Bytes.new('this is a string')
mv = Fiddle::MemoryView.new(bytestring)
mv[0] # 116
```
similary String.new('this is a string').bytes == ByteArray.new('this is a string') # a mutable byte array object that implements memoryview , takes an optional encoding that uses current string encoding
``` ruby
ba = ByteArray.new('this is a string')
mv = Fiddle::MemoryView.new(ba)
mv[0] # 116
mv[0] = 120 # memoryview works on underlying object - changes mv.obj
ba.pack('C*').force_encoding('UTF-8') # 'xhis is a string'
```
also it would be good if String#bytes returns the new classes - (return something that implements memoryview) not just plain array
or add a new %b literal that returns an immutable ByteString %b('this is a string')
