Does Solidity language has namespace?

Question

In Solidity langugae, I define ContractA and ContractB.

Inside ContractA declare structure A and I want to access A inside ContractB.

contract ContractA {
  struct A {
  uint age;
  string name;
  }

  // Some other methods and data structure
}

contract ContractB {
  // how to access structure A.
}

I don't want to use Inheritance or library syntax.
