6/// Removes surrounding double quotes from a string.
7///
8/// This macro takes an expression that evaluates to a string and returns a new `String`
9/// with any leading or trailing double quotes removed. It's useful for cleaning up
10/// string data that might be inadvertently wrapped in quotes, such as JSON string values.
11///
12/// # Arguments
13///
14/// * `$str`: An expression that can be converted into a string slice (`&str`).
15///
16/// # Examples
17///
18/// ```rust
19/// use your_crate::dequote; // Assuming `dequote` is re-exported or in scope
20///
21/// let quoted_string = "\"hello world\"";
22/// let dequoted_string = dequote!(quoted_string);
23/// assert_eq!(dequoted_string, "hello world");
24///
25/// let already_clean = "no quotes";
26/// let dequoted_clean = dequote!(already_clean);
27/// assert_eq!(dequoted_clean, "no quotes");
28/// ```
29macro_rules! dequote {
30    ($str:expr) => {
31        $str.trim_matches('"').to_string()

35/// The main home page component of the application.
36///
37/// This component displays different content based on whether the logged-in user
38/// is an administrator. It fetches the user's admin status from the
39/// `/api/users/current` endpoint upon initialization.
40///
41/// # Behavior
42/// - **Loading**: Displays "Loading..." while fetching user data.
43/// - **Admin User**: Renders the `TicketCount` utility component.
44/// - **Non-Admin User**: Renders the `TicketCount` utility component.
45///
46/// # Example
47/// ```rust
48/// html! {
49///     <Home />
50/// }
51/// ```
52#[component(Home)]

91/// A basic component displayed when a requested route does not match any defined paths (404 error).
92///
93/// It provides a simple message indicating that the page was not found and includes
94/// a link to navigate back to the home page.
95///
96/// # Example
97/// ```rust
98/// html! {
99///     <NotFound />

110    }
111}
112
113/// A component displayed when a user attempts to access a page for which they do not have sufficient permissions.
114///
115/// It informs the user about the access restriction and provides instructions to contact
116/// a specific person ("Herr Winter") if they believe this is an error.
117/// It also includes a link to return to the home page.
118///
119/// # Example
120/// ```rust
121/// html! {
122///     <PermissionDenied />
123/// }
