• Provide a Serializer impl that can write primitives and unit variants to a &mut fmt::Formatter (#1705, thanks @jethrogb)

  use serde::Serialize;
  use std::fmt::{self, Display};
  
  #[derive(Serialize)]
  #[serde(rename_all = "kebab-case")]
  pub enum MessageType {
      StartRequest,
      EndRequest,
  }
  
  impl Display for MessageType {
      fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
          self.serialize(f)
      }
  }
