// breaking change, they are defined here. When the next breaking change comes,
// they should be moved to the

//
// The primary reason we can't move these to `tokio-codec` now is because,

// `Encoder` in tokio_io::codec. And `Decoder` and `Encoder` needs to reference
// `Framed`. So they all still need
// to still be in the same module.
