## Design ## Design
@ -35,7 +35,17 @@ The over-arching design goal is to resemble the interface and behavior of
`std::string` as much as possible. When any operation would exceed the `std::string` as much as possible. When any operation would exceed the
maximum allowed size of the string, `std::length_error` is thrown. All maximum allowed size of the string, `std::length_error` is thrown. All
algorithms which throw exceptions provide the strong exception safety algorithms which throw exceptions provide the strong exception safety
guarantee. guarantee. This is intended to be a drop in replacement for `std::string`.
All the operations for `fixed_string` work when the source is within the string itself.
The API of `fixed_string` only diverges from `std::string` in few places,
being `substr` for which this implementation returns a string view instead of `fixed_string,
and certain functions that will never throw are marked as `noexcept`, which diverges from
those of `std::string`. Every function that is in the C++20 specification of `std::string` is
present in this implementation, with the only difference being the lack of `constexpr`
for the time being. The avaliable overloads for `fixed_string` are identical to those
of `std::string`, except for `operator+` which is explicitly deleted as no reasonable implementation
would be possible, due to the difficulty in determining the size of the resulting `fixed_string`.
