Struct Login 

pub struct Login {
    _marker: PhantomData<()>,
    function_component: FunctionComponent<Self>,
}

A component providing a form for user login.

This component handles user authentication by collecting a username and password, then sending these credentials to the backend /api/login endpoint. It manages UI states for loading, errors, and success, and redirects to the home page on successful login.

State

Uses use_state hooks to manage:

• username, pwd: Values of the login form input fields.
• loading: A boolean to indicate if the login process is ongoing.
• error: A string to display any login error messages.
• success: A boolean to indicate if login was successful.

Form Submission

• Prevents default form submission behavior.
• Constructs a LoginScheme payload from the input fields.
• Sends a POST request to /api/login.
• On successful response (HTTP 200), sets success to true and redirects to crate::Route::Home.
• On error, updates the error state with the appropriate message.

Example

html! {
    <Login />
}
