+### What it does
+Checks for public types with a `pub fn new() -> Self` method and no
+implementation of
+[`Default`](https://doc.rust-lang.org/std/default/trait.Default.html).
+
+### Why is this bad?
+The user might expect to be able to use
+[`Default`](https://doc.rust-lang.org/std/default/trait.Default.html) as the
+type can be constructed without arguments.
+
+### Example
+```
+pub struct Foo(Bar);
+
+impl Foo {
+    pub fn new() -> Self {
+        Foo(Bar::new())
+    }
+}
+```
+
+To fix the lint, add a `Default` implementation that delegates to `new`:
+
+```
+pub struct Foo(Bar);
+
+impl Default for Foo {
+    fn default() -> Self {
+        Foo::new()
+    }
+}
+```
