To get a type that implements io Reader from a   byte slice  you can use bytes NewReader in the bytes package  r    bytes NewReader byteData   This will return a value of type bytes Reader which implements the io Reader  and io ReadSeeker  interface  Don t worry about them not being the same  quot type quot   io Reader is an interface and can be implemented by many different types  To learn a little bit more about interfaces in Go  read Effective Go  Interfaces and Types
