Review comment:
       it is a general buffer class, I wanted to ensure performance for the serialize/deserialize of the expressions with the ipc handler so I needed a buffer that could meet the io.Writer and io.Seeker interfaces efficiently and generate a `memory.Buffer` without extra copies of the data. That's why it's not exported from this package (doesn't start with an uppercase letter)
