router
only.Expand description
This module provides a context extension RouterParam
and
many endpoint wrappers like Router
, Dispatcher
and Guard
.
Example
use roa::router::{Router, RouterParam, get, allow};
use roa::{App, Context, Status, MiddlewareExt, Next};
use roa::http::{StatusCode, Method};
use roa::tcp::Listener;
use tokio::task::spawn;
async fn gate(_ctx: &mut Context, next: Next<'_>) -> Result<(), Status> {
next.await
}
async fn query(ctx: &mut Context) -> Result<(), Status> {
Ok(())
}
async fn create(ctx: &mut Context) -> Result<(), Status> {
Ok(())
}
async fn graphql(ctx: &mut Context) -> Result<(), Status> {
Ok(())
}
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let router = Router::new()
.gate(gate)
.on("/restful", get(query).post(create))
.on("/graphql", allow([Method::GET, Method::POST], graphql));
let app = App::new()
.end(router.routes("/api")?);
let (addr, server) = app.run()?;
spawn(server);
let resp = reqwest::get(&format!("http://{}/api/restful", addr)).await?;
assert_eq!(StatusCode::OK, resp.status());
let resp = reqwest::get(&format!("http://{}/restful", addr)).await?;
assert_eq!(StatusCode::NOT_FOUND, resp.status());
Ok(())
}
Structs
An endpoint wrapper to dispatch requests by http method.
An endpoint wrapper to guard endpoint by http method.
An endpoint to route request by uri path.
A builder of RouteTable
.
Enums
Error occurring in building route table.
Traits
A context extension.
This extension must be used in Router
,
otherwise you cannot get expected router parameters.
