# Serialize Enum as Number (serde_repr Compatibility)

If you use the `#[repr(...)]` attribute on an enum to give it a C-like representation, then you may also want to use the [serde_repr](https://github.com/dtolnay/serde-repr) crate to serialize the enum values as numbers. In this case, you should use the corresponding `JsonSchema_repr` derive to ensure the schema for your type reflects how serde formats your type.
