Struct RouterBuilder

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

A builder for constructing routers with a fluent API.

This type provides a more ergonomic way to create and configure routers compared to using Router directly. It supports method chaining and handles all the type complexity internally.

Examples

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

#[derive(Clone)]
struct State {}

async fn get_users(ctx: RouteContext<State, ApiGatewayV2httpRequest>) -> Result<Value, Error> {
    Ok(json!({ "users": [] }))
}

async fn create_user(ctx: RouteContext<State, ApiGatewayV2httpRequest>) -> Result<Value, Error> {
    Ok(json!({ "status": "created" }))
}

let router = RouterBuilder::<State, ApiGatewayV2httpRequest>::new()
    .route("GET", "/users", get_users)
    .route("POST", "/users", create_user)
    .build();

Implementations

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

pub fn build(self) -> Router<State, E>

Trait Implementations
