Dependency Injection

[the-moisrex]

An extension can specify the conditions that is required for a dependency to be constructed.

• Condition
• Constructor

struct user {
  std::string username;
};

struct injector {
  template <Traits TraitsType, typename C>
  static constexpr bool can_inject = std::invocable_with<C, user>;

  static constexpr user construct_injection(Context auto&& ctx) {
    return user{
      .username = ctx.header('username')
    };
  }
};

It's just an example here.

Dependency Injection is possible using Custom Bodies.
