Example

Schema

{
  "definitions": {
    "Data": {
      "type": "object",
      "properties": {
        "frequency": {
          "type": "number",
          "default": 0.1
        },
        "amount": {
          "type": "integer",
          "default": 42
        },
        "reason": {
          "type": "string",
          "default": "I'm a teapot"
        }
      }
    }
  }
}

Invocation

$ cargo typify --no-builder example.json

    where
        T: std::convert::TryFrom<u64>,
        <T as std::convert::TryFrom<u64>>::Error: std::fmt::Debug,
    {
        T::try_from(V).unwrap()
    }
    pub(super) fn data_reason() -> String {
        "I'm a teapot".to_string()
    }
}

Expected

frequency is expected to not be optional and use a default function like reason.

Thanks for this. Our handling of floats is pretty lousy right now since they don't come up much for our own uses. In the spirit of transparency, it's probably going to be a low priority for us to fix this.
