[Bug] Rust generation: Implement the serialize trait correctly for the `TupleArray`

[MathieuDutSik]

🐛 Bug

The serialize trait is not correctly implemented for generated code in rust.

To reproduce

The following code does not pass

Signature:
  NEWTYPESTRUCT:
    TUPLEARRAY:
      CONTENT: U8
      SIZE: 64

The generated rust code is

#[derive(Clone, Debug, PartialEq, PartialOrd, Serialize, Deserialize)]
pub struct Signature(pub [u8; 64]);

and it does not compile since there is no serialization/deserialization implementations for [u8; 64].

I think here

Expected Behavior

I think implementing the trait in the generated code is the way forward.

System information

The bug is generic.

Additional context

None.
