* The parser can parse both absolute and relative URLs. If a relative URL is given, a base URL must also be given
* so that an absolute URL can be resolved. It can also parse individual parts of a URL when the default starting
* state is overridden, however, a previously parsed URL record object must be provided in this case.
*
* @see https://url.spec.whatwg.org/#concept-basic-url-parser
*
* @param \Rowbot\URL\String\USVStringInterface $input A UTF-8 encoded string consisting of only scalar
* values, excluding surrogates.
* @param \Rowbot\URL\URLRecord|null $base (optional) This represents the base URL, which in
* most cases, is the document's URL, it may also be
* a node's base URI or whatever base URL you wish to
* resolve relative URLs against. Default is null.
* @param string|null $encodingOverride (optional) Overrides the default ouput encoding,
* which is UTF-8. This option exists solely for the
* use of the HTML specification and should never be
* changed.
* @param \Rowbot\URL\URLRecord|null $url (optional) This represents an existing URL record
* object that should be modified based on the input
* URL and optional base URL. Default is null.
* @param \Rowbot\URL\State\State|null $stateOverride (optional) An object implementing the
* \Rowbot\URL\State interface that overrides the
* default start state, which is the Scheme Start
* State. Default is null.
*
* @return \Rowbot\URL\URLRecord|false Returns a URL object upon successfully parsing the input or false if parsing
* input failed.
