Problem description

Would like to modify an array which is declared in C++ struct and assigned with default value

Reproducible example code

• C++

class Math{
struct Data
{
  std::array<float, 5> id_ = {0}; // all value set to ZERO
  std::array<uint32_t, 5> length_ = {0}; // all value set to ZERO
  std::array<bool, 5> status_ = {0}; // all value set to ZERO
  float x_ = 7.5;
};
};

• I am avoiding whole code which has to bind (considering, module name is do_math)

.def_readwrite("id_", &Math::Data::id_)
.def_readwrite("length_", &Math::Data::length_)
.def_readwrite("status_", &Math::Data::status_)
.def_readwrite("x_", &Math::Data::x_)

• Now, I would like to modify all std::array member value. i am only showing here id_.
• In py file I can access the id_ member variable and it prints [0.0, 0.0, 0.0, 0.0, 0.0] as well as the x_ which output is 7.5

import do_math
struct_obj = do_math.Data()
print(struct_obj.id_)
print(struct_obj.x_)

• Now would like to modify the value of id_ but here I am unable to do it.

struct_obj.id_[2] = 2.2 # cannot modify
struct_obj.x_ = 1.5 # it is modified

Still output of struct_obj.id_ is [0.0, 0.0, 0.0, 0.0, 0.0] while struct_obj.x_ is changed to 1.5. How can I modify the id_ array in python?

Start at the .def_readwrite bindings for the std::array members and trace how the exposed array is read and written from Python. Reproduce the id_[2] assignment alongside the working x_ assignment, then verify that a supported binding behavior allows changes to persist in the C++ object.
