Struct Router

pub struct Router<State, E>
where
    State: Send + Sync + Clone + 'static,
    E: RoutableHttpEvent,
{ /* private fields */ }

The main router type that handles HTTP requests and dispatches them to handlers.

The router matches incoming requests against registered routes and executes the corresponding handlers. It supports path parameters and different HTTP methods.

Type Parameters

• State - The type of the application state shared across handlers
• E - The Lambda event type (must implement RoutableHttpEvent)

Examples

use lambda_lw_http_router_core::{Router, RouteContext};
use serde_json::{json, Value};
use lambda_runtime::Error;
use aws_lambda_events::apigw::ApiGatewayV2httpRequest;

#[derive(Clone)]
struct State {}

let mut router: Router<State, ApiGatewayV2httpRequest> = Router::new();
router.register_route("GET", "/hello/{name}", |ctx| async move {
    let name = ctx.params.get("name").map_or("World", String::as_str);
    Ok(json!({ "message": format!("Hello, {}!", name) }))
});

Implementations

impl<State, E> Router<State, E>

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

pub fn new() -> Router<State, E>

pub fn register_route<F, Fut>(&mut self, method: &str, path: &str, handler: F)

where F: Fn(RouteContext<State, E>) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<Value, Box<dyn Error + Send + Sync>>> + Send + 'static,

pub async fn handle_request( &self, event: LambdaEvent<E>, state: Arc<State>, ) -> Result<Value, Box<dyn Error + Send + Sync>>

Trait Implementations

impl<State, E> Default for Router<State, E>

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

fn default() -> Router<State, E>

Returns the “default value” for a type.
