Make web::Path innards public #3588
Conversation
So we can do something like this:
```
async fn delete_channel_message(
web::Path((channel_id, message_id)): web::Path<(Snowflake, Snowflake)>,
) {
// here channel_id and message_id are Snowflakes,
// and not web::Path<Snowflake>
}
```
Dunno why other web types are public and this is not.

Okey, I get it. |

No rush. Like I say, this will need to wait for v5.0. |
@robjtede: Deref impl [with public Path contents] allowed access to tuple elements like path.1 but then path.0.1 also worked so it was weird.
