in 4.0.0-beta.3: expected tuple struct or tuple variant, found struct web::Path

[rich-murphey]

Expected Behavior

Migration.md says this should work:

// Or (this wasn't previously supported):
async fn some_route(web::Path((first_name, last_name)): web::Path<(String, String)>) -> String {
  format!("Hello, {} {}", first_name, last_name)
}

Current Behavior

error[E0532]: expected tuple struct or tuple variant, found struct `web::Path`
   |
73 | async fn test(web::Path((first_name, last_name)): web::Path<(String, String)>) -> String {
   |               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: use struct pattern syntax instead: `web::Path { 0 }`
   |

   |

   | ---------------------- `web::Path` defined here
error: aborting due to previous error

Possible Solution

I don't know. I'm pretty sure I've used this in previous versions, so I'm guessing it's possible.
I haven't researched it yet, so I could be wrong.

Steps to Reproduce (for bugs)

compile the above function.

Context

I'm trying to do exactly what the above function does.

Your Environment

• Rust Version (I.e, output of rustc -V): rustc 1.50.0 (cb75ad5db 2021-02-10)
