+## patterns-in-fns-without-body
+
+This lint detects patterns in functions without body were that were
+previously erroneously allowed. Some example code that triggers this lint:
+
+```rust,compile_fail
+trait Trait {
+    fn foo(mut arg: u8);
+}
+```
+
+This will produce:
+
+```text
+warning: patterns aren't allowed in methods without bodies
+ --> src/main.rs:2:12
+  |
+2 |     fn foo(mut arg: u8);
+  |            ^^^^^^^
+  |
+  = note: `#[warn(patterns_in_fns_without_body)]` on by default
+  = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
+  = note: for more information, see issue #35203 <https://github.com/rust-lang/rust/issues/35203>
+```
+
+To fix this, remove the pattern; it can be used in the implementation without
+being used in the definition. That is:
+
+```rust
+trait Trait {
+    fn foo(arg: u8);
+}
+
+impl Trait for i32 {
+    fn foo(mut arg: u8) {
+
+    }
+}
