Route Guard mechanism about salvo HOT 8 CLOSED

I don't quite understand the feature you said, can you give example actix code about it?

https://docs.rs/actix-web/3.3.3/actix_web/guard/index.html
A guard is simply a function which returns a boolean which determines if the route could be navigated to or not. This function gets invoked before the route gets executed and if the function returns false, the route does not get executed and may return 404 or 401 as configured.

It looks like Router's filter. In salvo, Router::get, Router::post... are just filter.

Seems like the correct solution.

• filter_fn can't be async is there any other way to , let say in filter_fn must do some async validation operation
• should in async scenario to be hoop with async_trait

from salvo.

is it possible to have routes guard/grant by roles some thing like https://crates.io/crates/actix-web-grants

from salvo.

Filter is not supports async in current version.
If you want to protected your router, you can use middleware.

Router::with_path("aaa").push(Router::with_hoop(check).path("bb"))

For anyone interested: https://github.com/DDtKey/protect-endpoints now supports salvo 🎉
