Struct catalyzer::App

pub struct App<State = ()> { /* private fields */ }

The main application type.

See the module-level documentation for more information.

Implementations

impl<S, State> App<State>

where State: Clone + Send + Sync + 'static, Router<State>: for<'a> Service<IncomingStream<'a>, Error = Infallible, Response = S> + Send + 'static, for<'a> <Router<State> as Service<IncomingStream<'a>>>::Future: Send, S: Service<RawRequest, Response = RawResponse, Error = Infallible> + Clone + Send + 'static, S::Future: Send,

pub async fn launch(self) -> Result<CatalyzedApp<S, State>>

Catalyzes the application and launches it.

This should be the last method called on the App instance.

impl<State> App<State>

where State: Clone + Send + Sync + 'static,

pub fn new() -> Self

Creates a new App instance.

This is the main entry point for creating a new application.

It is recommended to use the App! macro instead of this method.

pub fn route<Return, Meta, Handler>(self, handler: Handler) -> Result<Self>

where Handler: AxumHandler<Return, State>, Meta: HandlerMetadata, Return: 'static,

Mounts a route handler on the application.

This requires a handler that implements the AxumHandler trait. Additionally, you need to provide a metadata type that implements the HandlerMetadata trait.

Example

#[get("/")]
fn index() {
    "Hello, world!"
}
 
let app = App::new()
    .route::<_, index_metadata, _>(index)?;

pub fn bind<Addr>(self, addr: Addr) -> Result<Self>

where Addr: ToSocketAddrs,

Binds the application to a specific address.

This is required before launching the application.

Example

let app = App::new().bind("0.0.0.0:8080")?;// Localhost on port 8080

pub fn set_state<S2>(self, state: State) -> App<S2>

Sets the state of the application.

If your application requires a state, you must set it using this method.

Example

struct AppState {
    counter: u32,
}
 
let app = App::new()
    .set_state(AppState { counter: 0 });

Trait Implementations

impl<State: Debug> Debug for App<State>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
