+# Rust SmartDefault
+
+Custom derive for automatically implementing the `Default` trait with customized default values:
+
+```rust
+#[macro_use]
+extern crate smart_default;
+
+#[derive(SmartDefault)]
+enum Foo {
+    Bar,
+    #[default]
+    Baz {
+        #[default = 12]
+        a: i32,
+        b: i32,
+        #[default(Some(Default::default()))]
+        c: Option<i32>,
+        #[default(_code = "vec![1, 2, 3]")]
+        d: Vec<u32>,
+        #[default = "four"]
+        e: String,
+    },
+    Qux(i32),
+}
+
+assert!(Foo::default() == Foo::Baz {
+    a: 12,
+    b: 0,
+    c: Some(0),
+    d: vec![1, 2, 3],
+    e: "four".to_owned(),
+});
+```
+
+Requires Rust 1.30+ (for non-string values in attributes)
