#[derive(EnumConvertFromInt)]

    // Attributes available to this derive:
    #[EnumConvertFromIntFallback]
}

Emit an std::convert::From<i32> implementation for an enum type. When converting from an i32 that does not have an enumeration value, the system will panic, unless a fallback enumeration symbol is specified with #[EnumConvertFromIntFallback = "Identifier"].
