C++ Equivalent of Python List of Dictionaries?

I have a Python list of dictionaries that contain information about individual layers of a neural network. Each dictionary can have any number of entries, including more dictionaries.

layer_config = [
 {'conv_layer': {
     'filter_size' : 5,
     'stride' : 1,
     'num_filters' : 20}},
 {'pool_layer': {
     'poolsize' : (2,2)}},
 {'fc_layer': {
     'num_output' : 30}},
 {'final_layer': {
     'num_classes' : 10}}
]

I am converting the program into C++ and need to find a way to organize this information in a similar manner. Are C++ nested maps the best way to accomplish this, or is there another data structure out there that might be a better alternative?
