`swap` overloads

== Synopses

Declared in `<bdljsn_error.h>`

Exchange the values of the specified `a` and `b` objects. This function provides the no‐throw exception‐safety guarantee if the two objects were created with the same allocator and the basic guarantee otherwise.

Exchange the value of the specified `a` `Json` object with that of the specified `b` `Json` object. If an exception is thrown, both objects are left in valid but unspecified states. This operation guarantees O[1] complexity. The behavior is undefined unless `a` was created with the same allocator as `b`.

Exchange the value of the specified `a` `JsonArray` with that of the specified `b` `JsonArray`. This function provides the no‐throw exception‐safety guarantee. This operation has O[1]complexity if `a` was created with the same allocator as `b`; otherwise, it has O[n+m] complexity, where n and m are the number of elements in `a` and `b`, respectively.

Exchange the values of the specified `a` and `b` objects. This exception provides the no‐throw exception‐safety guarantee. Note that, since `a` and `b` have the same value (a class invariant), this operation is a no‐op.
