Struct User

pub struct User {
    pub is_admin: bool,
    /* private fields */
}

The User guard can be used to restrict content so it can only be viewed by authenticated users.

#[get("/private-content")]
fn private_content(user: User) -> &'static str {
    "If you can see this, you are logged in."
}

Fields

is_admin: bool

Implementations

impl User

pub fn set_password(&mut self, new: &str) -> Result<(), Error>

This method allows to reset the password of a user. In order for the new password to be saved, it must be passed to a Users instance. This function is meant for cases where the user lost their password. In case the user is authenticated, you can change it more easily with change_password. This function will fail in case the password is not secure enough.

#[get("/reset-password/<id>/<new_password>")]
async fn reset_password(id: i32, new_password: String, users: &State<Users>) -> Result<(), Error> {
    let mut user = users.get_by_id(id).await?;
    user.set_password(&new_password);
    users.modify(&user).await?;
    Ok(())
}

pub fn id(&self) -> i32

This is an accessor function for the private id field. This field is private so it is not modified by accident when updating a user.

#[get("/show-my-id")]
fn show_my_id(user: User) -> String {
    format!("Your user_id is: {}", user.id())
}

pub fn email(&self) -> &str

This is an accessor field for the private email field. This field is private so an email cannot be updated without checking whether it is valid.

#[get("/show-my-email")]
fn show_my_email(user: User) -> String {
    format!("Your user_id is: {}", user.email())
}

pub fn set_email(&mut self, email: &str) -> Result<(), Error>

This functions allows to easily modify the email of a user. In case the input is not a valid email, it will return an error. In case the user corresponds to the authenticated client, it’s easier to use Auth::change_email.

#[get("/set-email/<email>")]
async fn set_email(email: String, auth: Auth<'_>) -> Result<String, Error> {
    let mut user = auth.get_user().await.unwrap();
    user.set_email(&email)?;
    auth.users.modify(&user).await?;
    Ok("Your user email was changed".into())
}
