v1.0.97

• Introduce serde(try_from = "...") attribute to derive Deserialize based on a given implementation of std::convert::TryFrom (#1526, thanks @fanzeyi)

  #[derive(Deserialize)]
  #[serde(try_from = "u32")]
  enum N {
      Zero,
      One,
      Two,
  }
  
  impl TryFrom<u32> for N {
      type Error = String;
  
      fn try_from(u: u32) -> Result<Self, Self::Error> {
          match u {
              0 => Ok(Self::Zero),
              1 => Ok(Self::One),
              2 => Ok(Self::Two),
              other => Err(format!("out of range: {}", other)),
          }
      }
  }
