What
--
Define a new `route` attribute macro that supports defining multiple
HTTP methods to routed to (handled by) a single handler.
The attribute macro syntax looks like this
```rust
use actix_web::route;
async fn multi_methods() -> &'static str {
"Hello world!\r\n"
}
```
How
--
This implementation extends the [`GuardType`][1] enum in actix-web-codegen to have a
new `GuardType::Multi` variant that denotes when multiple method guards
are used.
A new `methods` attribute in the `route` attribute macro provides a
comma-separated list of HTTP methods to provide guard for.
The code parses the methods list, matches them to the respective
`GuardType` and uses the `AnyGuard` struct to combine them together.
A constructor method for [`AnyGuard`][2] is added to support this.
The generated code looks like this:
```rust
pub struct multi_methods;
impl actix_web::dev::HttpServiceFactory for multi_methods {
fn register(self, __config: &mut actix_web::dev::AppService) {
¦ async fn multi_methods() -> &'static str {
¦ ¦ "Hello world!\r\n"
¦ }
¦ let __resource = actix_web::Resource::new("/multi")
¦ ¦ .name("multi_methods")
¦ ¦ .guard(actix_web:💂:AnyGuard::new(<[_]>::into_vec(box [
¦ ¦ ¦ Box::new(actix_web:💂:Get()),
¦ ¦ ¦ Box::new(actix_web:💂:Post()),
¦ ¦ ])))
¦ ¦ .to(multi_methods);
¦ actix_web::dev::HttpServiceFactory::register(__resource, __config)
}
}
```
**NOTE: This is my first attempt that implementing this feature.
Feedback and mentorship is highly welcome to improve it :-)**
