Crate axum_flash
source ·Expand description
One-time notifications (aka flash messages) for axum.
Example
use axum::{
response::{IntoResponse, Redirect},
extract::FromRef,
routing::get,
Router,
};
use axum_flash::{IncomingFlashes, Flash, Key};
#[derive(Clone)]
struct AppState {
flash_config: axum_flash::Config,
}
let app_state = AppState {
// The key should probably come from configuration
flash_config: axum_flash::Config::new(Key::generate()),
};
// Our state type must implement this trait. That is how the config
// is passed to axum-flash in a type safe way.
impl FromRef<AppState> for axum_flash::Config {
fn from_ref(state: &AppState) -> axum_flash::Config {
state.flash_config.clone()
}
}
let app = Router::new()
.route("/", get(root))
.route("/set-flash", get(set_flash))
.with_state(app_state);
async fn root(flashes: IncomingFlashes) -> IncomingFlashes {
for (level, text) in &flashes {
// ...
}
// The flashes must be returned so the cookie is removed
flashes
}
async fn set_flash(flash: Flash) -> (Flash, Redirect) {
(
// The flash must be returned so the cookie is set
flash.debug("Hi from flash!"),
Redirect::to("/"),
)
}
