    /// The [`Uri`][crate::Uri] type and related functions can be used to parse URIs into
    /// their components, and build valid URIs from individual components.
    ///
    /// Note that [`Uri`][crate::Uri] scope is to help manipulate URIs in various applications,
    /// following [RFC 3986](https://tools.ietf.org/html/rfc3986). In particular,
    /// it doesn't intend to cover web browser needs, and doesn't implement the
    /// [WHATWG URL](https://url.spec.whatwg.org/) standard. No APIs are provided to
    /// help prevent
    /// [homograph attacks](https://en.wikipedia.org/wiki/IDN_homograph_attack), so
    /// [`Uri`][crate::Uri] is not suitable for formatting URIs for display to the user for making
    /// security-sensitive decisions.
    ///
    /// ## Relative and absolute URIs # {`relative`-absolute-uris}
    ///
    /// As defined in [RFC 3986](https://tools.ietf.org/html/rfc3986`section`-4), the
    /// hierarchical nature of URIs means that they can either be ‘relative
    /// references’ (sometimes referred to as ‘relative URIs’) or ‘URIs’ (for
    /// clarity, ‘URIs’ are referred to in this documentation as
    /// ‘absolute URIs’ — although
    /// [in constrast to RFC 3986](https://tools.ietf.org/html/rfc3986`section`-4.3),
    /// fragment identifiers are always allowed).
    ///
    /// Relative references have one or more components of the URI missing. In
    /// particular, they have no scheme. Any other component, such as hostname,
    /// query, etc. may be missing, apart from a path, which has to be specified (but
    /// may be empty). The path may be relative, starting with `./` rather than `/`.
    ///
    /// For example, a valid relative reference is `./path?query`,
    /// `/?query`fragment`` or `//example.com`.
    ///
    /// Absolute URIs have a scheme specified. Any other components of the URI which
    /// are missing are specified as explicitly unset in the URI, rather than being
    /// resolved relative to a base URI using [`parse_relative()`][Self::parse_relative()].
    ///
    /// For example, a valid absolute URI is `file:///home/bob` or
    /// `https://search.com?query=string`.
    ///
    /// A [`Uri`][crate::Uri] instance is always an absolute URI. A string may be an absolute URI
    /// or a relative reference; see the documentation for individual functions as to
    /// what forms they accept.
    ///
    /// ## Parsing URIs
    ///
    /// The most minimalist APIs for parsing URIs are [`split()`][Self::split()] and
    /// [`split_with_user()`][Self::split_with_user()]. These split a URI into its component
    /// parts, and return the parts; the difference between the two is that
    /// [`split()`][Self::split()] treats the ‘userinfo’ component of the URI as a
    /// single element, while [`split_with_user()`][Self::split_with_user()] can (depending on the
    /// [`UriFlags`][crate::UriFlags] you pass) treat it as containing a username, password,
    /// and authentication parameters. Alternatively, [`split_network()`][Self::split_network()]
    /// can be used when you are only interested in the components that are
    /// needed to initiate a network connection to the service (scheme,
    /// host, and port).
    ///
    /// [`parse()`][Self::parse()] is similar to [`split()`][Self::split()], but instead of returning
    /// individual strings, it returns a [`Uri`][crate::Uri] structure (and it requires
    /// that the URI be an absolute URI).
    ///
    /// [`resolve_relative()`][Self::resolve_relative()] and [`parse_relative()`][Self::parse_relative()] allow you to
    /// resolve a relative URI relative to a base URI.
    /// [`resolve_relative()`][Self::resolve_relative()] takes two strings and returns a string,
    /// and [`parse_relative()`][Self::parse_relative()] takes a [`Uri`][crate::Uri] and a string and returns a
    /// [`Uri`][crate::Uri].
    ///
    /// All of the parsing functions take a [`UriFlags`][crate::UriFlags] argument describing
    /// exactly how to parse the URI; see the documentation for that type
    /// for more details on the specific flags that you can pass. If you
    /// need to choose different flags based on the type of URI, you can
    /// use [`peek_scheme()`][Self::peek_scheme()] on the URI string to check the scheme
    /// first, and use that to decide what flags to parse it with.
    ///
    /// For example, you might want to use [`UriParamsFlags::WWW_FORM`][crate::UriParamsFlags::WWW_FORM] when parsing the
    /// params for a web URI, so compare the result of [`peek_scheme()`][Self::peek_scheme()] against
    /// `http` and `https`.
    ///
    /// ## Building URIs
    ///
    /// [`join()`][Self::join()] and [`join_with_user()`][Self::join_with_user()] can be used to construct
    /// valid URI strings from a set of component strings. They are the
    /// inverse of [`split()`][Self::split()] and [`split_with_user()`][Self::split_with_user()].
    ///
    /// Similarly, [`build()`][Self::build()] and [`build_with_user()`][Self::build_with_user()] can be used to
    /// construct a [`Uri`][crate::Uri] from a set of component strings.
    ///
    /// As with the parsing functions, the building functions take a
    /// [`UriFlags`][crate::UriFlags] argument. In particular, it is important to keep in mind
    /// whether the URI components you are using are already `%`-encoded. If so,
    /// you must pass the [`UriFlags::ENCODED`][crate::UriFlags::ENCODED] flag.
    ///
    /// ## `file://` URIs
    ///
    /// Note that Windows and Unix both define special rules for parsing
    /// `file://` URIs (involving non-UTF-8 character sets on Unix, and the
    /// interpretation of path separators on Windows). [`Uri`][crate::Uri] does not
    /// implement these rules. Use `g_filename_from_uri()` and
    /// `g_filename_to_uri()` if you want to properly convert between
    /// `file://` URIs and local filenames.
    ///
    /// ## URI Equality
    ///
    /// Note that there is no `g_uri_equal ()` function, because comparing
    /// URIs usefully requires scheme-specific knowledge that [`Uri`][crate::Uri] does
    /// not have. [`Uri`][crate::Uri] can help with normalization if you use the various
    /// encoded [`UriFlags`][crate::UriFlags] as well as `G_URI_FLAGS_SCHEME_NORMALIZE` however
    /// it is not comprehensive.
    /// For example, `data:,foo` and `data:;base64,Zm9v` resolve to the same
    /// thing according to the `data:` URI specification which GLib does not
    /// handle.
