> Currently Thrift structs are turned into Rust {{struct}} definitions that do not have an auto-derived {{Hash}}. We should auto-derive this trait.
> The following behaviors should be checked:
> # Can still derive {{Hash}} even if the struct contains a {{double}}
> # Can still derive {{Hash}} even if the struct contains {{set<double>}}
> # Can still derive {{Hash}} even if the struct contains {{map<double, double>}}
> Basically, doubles are represented in the auto-generated code by {{OrderedFloat}} instead of {{f64}} since we cannot derive a hash for, or order Rust floats. The resulting code should work even if doubles are contained any where in the structure.
