-### What it does
-Lint for redundant pattern matching over `Result`, `Option`,
-`std::task::Poll` or `std::net::IpAddr`
-
-### Why is this bad?
-It's more concise and clear to just use the proper
-utility function
-
-### Known problems
-This will change the drop order for the matched type. Both `if let` and
-`while let` will drop the value at the end of the block, both `if` and `while` will drop the
-value before entering the block. For most types this change will not matter, but for a few
-types this will not be an acceptable change (e.g. locks). See the
-[reference](https://doc.rust-lang.org/reference/destructors.html#drop-scopes) for more about
-drop order.
-
-### Example
-```
-if let Ok(_) = Ok::<i32, i32>(42) {}
-if let Err(_) = Err::<i32, i32>(42) {}
-if let None = None::<()> {}
-if let Some(_) = Some(42) {}
-if let Poll::Pending = Poll::Pending::<()> {}
-if let Poll::Ready(_) = Poll::Ready(42) {}
-if let IpAddr::V4(_) = IpAddr::V4(Ipv4Addr::LOCALHOST) {}
-if let IpAddr::V6(_) = IpAddr::V6(Ipv6Addr::LOCALHOST) {}
-match Ok::<i32, i32>(42) {
- Ok(_) => true,
- Err(_) => false,
-};
-```
-
-The more idiomatic use would be:
-
-```
-if Ok::<i32, i32>(42).is_ok() {}
-if Err::<i32, i32>(42).is_err() {}
-if None::<()>.is_none() {}
-if Some(42).is_some() {}
-if Poll::Pending::<()>.is_pending() {}
-if Poll::Ready(42).is_ready() {}
-if IpAddr::V4(Ipv4Addr::LOCALHOST).is_ipv4() {}
-if IpAddr::V6(Ipv6Addr::LOCALHOST).is_ipv6() {}
-Ok::<i32, i32>(42).is_ok();
