/**
 * GUriFlags:
 * @G_URI_FLAGS_NONE: No flags set.
 * @G_URI_FLAGS_PARSE_RELAXED: Parse the URI more relaxedly than the
 *     [RFC 3986](https://tools.ietf.org/html/rfc3986) grammar specifies,
 *     fixing up or ignoring common mistakes in URIs coming from external
 *     sources. This is also needed for some obscure URI schemes where `;`
 *     separates the host from the path. Don’t use this flag unless you need to.
 * @G_URI_FLAGS_HAS_PASSWORD: The userinfo field may contain a password,
 *     which will be separated from the username by `:`.
 * @G_URI_FLAGS_HAS_AUTH_PARAMS: The userinfo may contain additional
 *     authentication-related parameters, which will be separated from
 *     the username and/or password by `;`.
 * @G_URI_FLAGS_NON_DNS: The host component should not be assumed to be a
 *     DNS hostname or IP address (for example, for `smb` URIs with NetBIOS
 *     hostnames).
 * @G_URI_FLAGS_ENCODED: When parsing a URI, this indicates that `%`-encoded
 *     characters in the userinfo, path, query, and fragment fields
 *     should not be decoded. (And likewise the host field if
 *     %G_URI_FLAGS_NON_DNS is also set.) When building a URI, it indicates
 *     that you have already `%`-encoded the components, and so #GUri
 *     should not do any encoding itself.
 * @G_URI_FLAGS_ENCODED_QUERY: Same as %G_URI_FLAGS_ENCODED, for the query
 *     field only.
 * @G_URI_FLAGS_ENCODED_PATH: Same as %G_URI_FLAGS_ENCODED, for the path only.
 * @G_URI_FLAGS_ENCODED_FRAGMENT: Same as %G_URI_FLAGS_ENCODED, for the
 *     fragment only.
 * @G_URI_FLAGS_SCHEME_NORMALIZE: A scheme-based normalization will be applied.
 *     For example, when parsing an HTTP URI changing omitted path to `/` and
 *     omitted port to `80`; and when building a URI, changing empty path to `/`
 *     and default port `80`). This only supports a subset of known schemes. (Since: 2.68)
 *
 * Flags that describe a URI.
 *
 * When parsing a URI, if you need to choose different flags based on
 * the type of URI, you can use g_uri_peek_scheme() on the URI string
 * to check the scheme first, and use that to decide what flags to
 * parse it with.
 *
 * Since: 2.66
