| <p>A range of positions can be used for slicing <code>Url</code>:</p> |

| <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">let </span>serialization: <span class="kw-2">&</span>str = <span class="kw-2">&</span>some_url[..]; |

| <p>In a pseudo-grammar (where <code>[</code>…<code>]?</code> makes a sub-sequence optional), |
| URL components and delimiters that separate them are:</p> |
| <div class="example-wrap"><pre class="language-notrust"><code>url = |
| scheme ":" |
| [ "//" [ username [ ":" password ]? "@" ]? host [ ":" port ]? ]? |
| path [ "?" query ]? [ "#" fragment ]?</code></pre></div> |
| <p>When a given component is not present, |
| its “before” and “after” position are the same |
| (so that <code>&some_url[BeforeFoo..AfterFoo]</code> is the empty string) |
| and component ordering is preserved |
| (so that a missing query “is between” a path and a fragment).</p> |
| <p>The end of a component and the start of the next are either the same or separate |
| by a delimiter. |
| (Not that the initial <code>/</code> of a path is considered part of the path here, not a delimiter.) |
| For example, <code>&url[..BeforeFragment]</code> would include a <code>#</code> delimiter (if present in <code>url</code>), |
| so <code>&url[..AfterQuery]</code> might be desired instead.</p> |
| <p><code>BeforeScheme</code> and <code>AfterFragment</code> are always the start and end of the entire URL, |
| so <code>&url[BeforeScheme..X]</code> is the same as <code>&url[..X]</code> |
| and <code>&url[X..AfterFragment]</code> is the same as <code>&url[X..]</code>.</p> |
