-### Ox String Types
-
-Ox has six different major string types.
-These types are divided into two categories: store types and view types.
-
-String stores maintain a copy of the string data, whereas view types only
-maintain a reference to the data.
-Views should be used where you otherwise might use a const reference to a
-string store type.
-
-Having all of these different string types may sound like an interoperability
-nightmare, but taking string view types extensively where applicable makes the
-imagined interoperability issues virtually non-existent.
-
-#### String Store Types
-
-##### String / BasicString
-
-```ox::String```, or really ```ox::BasicString```, is Ox's version of
-```std::string```.
-Like ```std::string```, ```String``` allocates to store the string data.
-Also like ```std::string```, ```String``` allows for small string
-optimization for strings under 8 bytes.
-Unlike ```std::string```, the template that ```String``` is based on,
-```BasicString```, takes a parameter that allows adjusting to different size
-small string buffers.
-```ox::String``` is an alias to ```ox::BasicString<8>```.
-
-```cpp
-// s can hold up to 100 bytes, plus one for a null terminator before allocating
-ox::BasicString<100> s;
-```
-Also unlike ```std::string```, ```ox::String``` has an explicit C-string conversion
-constructor.
-This prevents accidental instantiations of ```String```.
-
-Consider the following:
-
-```cpp
-void fStd(std::string const&);
-void fOx(ox::String const&);
-
-int main() {
-    // implicit and silent instantiation of std::string, which includes an
-    // allocation
-    fStd("123456789");
-    // Will fail to compile:
-    fOx("123456789");
-    // But explicit String instantiation will work:
-    fOx(ox::String{"123456789"});
-}
-```
-
-##### IString
-
-```IString```, or "inline string", is like ```BasicString```, but it will cut
-off strings that exceed that limit.
-
-```cpp
-ox::IString<5> s; // s can hold up to 5 characters, plus a null terminator
-s = "12345";      // valid
-s = "123456";     // will compile and run, but will get cut off at '5'
-```
-
-This is useful for certain string categories that have fixed lengths, like UUID
-strings or for numbers.
-
-Ox makes use of ```IString``` in the following ways:
-
-```cpp
-using UUIDStr = ox::IString<36>;
-
-// and
-
-template<Integer_c Integer>
-[[nodiscard]]
-constexpr auto intToStr(Integer v) noexcept {
-	constexpr auto Cap = [] {
-		auto out = 0;
-		switch (sizeof(Integer)) {
-			case 1:
-				out = 3;
-				break;
-			case 2:
-				out = 5;
-				break;
-			case 4:
-				out = 10;
-				break;
-			case 8:
-				out = 21;
-				break;
-		}
-		return out + ox::is_signed_v<Integer>;
-	}();
-	ox::IString<Cap> out;
-	std::ignore = out.resize(out.cap());
-	ox::CharBuffWriter w{{out.data(), out.cap()}};
-	std::ignore = writeItoa(v, w);
-	std::ignore = out.resize(w.tellp());
-	return out;
-}
-```
-
-##### StringParam
-
-```StringParam``` is a weird type.
-Because ```String::String(const char*)``` is explicit, it becomes a pain for
-functions to take ```String```s.
-
-```cpp
-struct Type {
-    ox::String m_s;
-    explicit Type(ox::String p): m_s(std::move(p)) {
-    }
-};
-
-void f() {
-    ox::String s{"asdf"};
-    Type t1{"asdf"};             // invalid - will not compile
-    Type t2{s};                  // invalid - will not compile
-    Type t3{std::move(s)};       // valid
-    Type t4{ox::String{"asdf"}}; // valid
-}
-```
-
-```StringParam``` has implicit conversion constructors, and will appropriately
-move from r-value ```String```s or create a ```String``` if not passed
-ownership of an existing ```String```.
-Think of ```StringParam``` as a way to opt-in to implicit instantiation with
-strings.
-
-```StringParam``` can access the string as a view through the ```view()```
-function, and the ```String``` inside can be accessed by moving from the
-```StringParam```.
-
-```cpp
-struct Type {
-    ox::String m_s;
-    explicit Type(ox::StringParam p): m_s(std::move(p)) {
-    }
-};
-
-void f() {
-    ox::String s{"asdf"};
-    Type t1{"asdf"};             // valid
-    Type t2{s};                  // valid
-    Type t3{std::move(s)};       // valid
-    Type t4{ox::String{"asdf"}}; // valid
-}
-```
-
-#### String View Types
-
-##### StringView
-
-```ox::StringView``` is Ox's version of ```std::string_view```.
-```StringView``` contains a pointer to a string, along with its size.
-
-This should be the normal type taken when a function needs a string that will
-exist until it returns.
-
-##### CStringView
-
-```CStringView``` is like ```StringView```, but it comes with the promise that
-the string ends with a null terminator.
-Accordingly, it has a ```c_str()``` function in addition to the ```data()```
-function that ```StringView``` has.
-
-```CStringView``` should be used when wrapping a C API that only takes C
-strings.
-
-##### StringLiteral
-
-```StringLiteral``` is a string view type, but it kind of straddles the line
-between view and store types.
-Creating a ```StringLiteral``` is a promise that you are passing a string
-literal into the constructor.
-This means you can treat it like a store, that can be safely used as a copy of
-the data.
-Functions that take ```StringLiteral```s are allowed to assume that the data
-will have no lifetime concerns and hold onto it without any need to make a
-copy.
-It has a consteval constructor to enforce the promise that it is a compile time
-string.
-
-```cpp
-void f(ox::StringLiteral const&);
-
-int main() {
-    f("123456789");                     // valid
-    f(ox::String{"123456789"}.c_str()); // invalid - will not compile
-}
-```
-
-#### Other Variants
-
-There are a few convenience aliases as well.
-
-* StringCR = String const&
-* StringViewCR = StringView const&
-* CStringViewCR = CStringView const&
-* CString = const char*
-
-String views do not generally need const references, but it does make debugging
-easier, as we can skip the constructor call if a string view already exists.
-
-These kind of aliases probably should not exist for most types, but strings are
-fundamental and ease of use is desirable.
-
