Will this cause build failure if you try to serialize a fixed length array longer than 32?
That's the reason the feature isn't already there, due to const generics not existing yet, and thus serde has that limitation.

The const generics function will be stable in version 1.51, and this defect may be improved in the future.

I still close the pr first.

Yeah once the feature is there, and serde implements it, adding serde support will be extremely simple, and I'd likely add it directly without any feature flags.

ok

Hi! It is Rust 1.54 already here. Can you add this feature or serde still doesn't support it?

@KrasnovPavel It still doesn't

serde-rs/serde#1937

In the meantime, I've added rosrust::Value and rosrust::MessageValue, which do support serde, and are just dynamic representations of ROS messages.

https://github.com/adnanademovic/rosrust/blob/master/rosrust/tests/dynamic_msg.rs#L100-L144

You can do .into() to convert into a Value/MessageValue, or ,try_from() to convert from an arbitrary one.
