 * or
 *               trustedResourceUrl`//example.com`;
 *
 * When this function is called with a template literal without any embedded
 * expressions, the template string may contain anything as the whole URL is
 * a compile-time string constant.
 *
 * When this function is called with a template literal that contains embedded
 * expressions, the template must start with one of the following:
 * - `https://<origin>/`
 * - `//<origin>/`
 * - `/<pathStart>`
 * - `about:blank`
 * - `data:`
 *
 * `<origin>` must contain only alphanumeric or any of the following: `-.:`.
 * Remember that, as per the documentation for TrustedResourceUrl, the origin
 * must be trustworthy. An origin of "example.com" could be set with this
 * method, but would tie the security of your site to the security of
 * example.com. Similarly, formats that potentially cover redirects hosted
 * on a trusted origin are problematic, since that could lead to untrusted
 * origins.
 *
 * `<pathStart>` is either an empty string, or a non empty string that does not
 * start with '/' or '\'.
 * In other words, `/<pathStart>` is either a '/' or a
 * '/' followed by at least one character that is not '/' or '\'.
 *
 * `data:` (data URL) does not allow embedded expressions in the template
 * literal input.
 *
 * All embedded expressions are URL encoded when they are interpolated. Do not
 * embed expressions that are already URL encoded as they will be double encoded
 * by the builder.

 * @param rest This represents the template's embedded expressions.
