+# Attributes for Crate Authors
+
+In some cases it is possible to extend Clippy coverage to 3rd party libraries.
+To do this, Clippy provides attributes that can be applied to items in the 3rd party crate.
+
+## `#[clippy::format_args]`
+
+_Available since Clippy v1.84_
+
+This attribute can be added to a macro that supports `format!`, `println!`, or similar syntax.
+It tells Clippy that the macro is a formatting macro, and that the arguments to the macro
+should be linted as if they were arguments to `format!`. Any lint that would apply to a
+`format!` call will also apply to the macro call. The macro may have additional arguments
+before the format string, and these will be ignored.
+
+### Example
+
+```rust
+/// A macro that prints a message if a condition is true.
+#[macro_export]
+#[clippy::format_args]
+macro_rules! print_if {
+    ($condition:expr, $($args:tt)+) => {{
+        if $condition {
+            println!($($args)+)
+        }
+    }};
+}
+```
+
+## `#[clippy::has_significant_drop]`
+
+_Available since Clippy v1.60_
+
+The `clippy::has_significant_drop` attribute can be added to types whose Drop impls have an important side effect,
+such as unlocking a mutex, making it important for users to be able to accurately understand their lifetimes.
+When a temporary is returned in a function call in a match scrutinee, its lifetime lasts until the end of the match
+block, which may be surprising.
+
+### Example
+
+```rust
+#[clippy::has_significant_drop]
+struct CounterWrapper<'a> {
+    counter: &'a Counter,
+}
+
+impl<'a> Drop for CounterWrapper<'a> {
+    fn drop(&mut self) {
+        self.counter.i.fetch_sub(1, Ordering::Relaxed);
+    }
+}
+```
