+# Implement "From" trait...
+
+Basic implementation of From trait to create "MyStruct" from<i32>
+```
+struct MyStruct{
+    word: String,
+    number: i32
+}
+
+impl From<i32> for MyStruct{
+    fn from(num: i32) -> MyStruct {
+        MyStruct {
+            word: "notset".to_string(),
+            number: num
+        }
+    }
+    
+}
+
+fn main() {
+    let m = MyStruct::from(25);
+    println!("Struct made: word={}, number={}.", m.word, m.number);
+}
+```
+
+## Output of above: 
+
+```
+Struct made: word=notset, number=25.
+```
