Note that this still keeps the old behaviour of putting things in std by default on serenity so the tools can be happy, but if USING_AK_GLOBALLY is unset, AK behaves like a good citizen and doesn't try to put things in the ::std namespace. std::nothrow_t and its friends get to stay because I'm being told that compilers assume things about them and I can't yeet them into a different namespace...for now.

// DeprecatedString is a convenience wrapper around StringImpl, suitable for passing
|
|
// around as a value type. It's basically the same as passing around a
|
|
// RefPtr<StringImpl>, with a bit of syntactic sugar.
|
|
//
|
|
// Note that StringImpl is an immutable object that cannot shrink or grow.
|
|
// Its allocation size is snugly tailored to the specific string it contains.
|
|
// Copying a DeprecatedString is very efficient, since the internal StringImpl is
|
|
// retainable and so copying only requires modifying the ref count.
|
|
//
|
|
// There are three main ways to construct a new DeprecatedString:
|
|
//
|
|
// s = DeprecatedString("some literal");
|
|
//
|
|
// s = DeprecatedString::formatted("{} little piggies", m_piggies);
|
|
//
|
|
// StringBuilder builder;
|
|
// builder.append("abc");
|
|
// builder.append("123");
|
|
// s = builder.to_deprecated_string();
