+
+### Specialities
+
+- High-level language features without performance penalties
+- Program behaviors can be enforced at compile time
+- Enhanced program reliability
+- Built—in dependency management, similar to npm
+- Quickly growing ecosystem of libraries
+- First-class multithreading
+    - Compiler error to improperly access shared data
+- Type system:
+    - Can uncover bugs at compile time
+    - Makes refactoring simple
+    - Reduces the number of tests needed
+- Module system makes code separation simple
+- Adding a dependency is 1 line in a config file
+- Tooling:
+    - Generate docs, lint code, auto format
+
+### Industries

+# Match
+
+Match expressions are similar to if else if
+
+It matches only on same type and accounts every possibility.
+Making code more robust
+
+It works on expressions instead of statements. Therefore, at the end of statement instead of `;` we will use `,`.
+
+```rust
+fn main() {
+    let some_int = 3;
+    match some_int {
+        1 => println!("its 1"),
+        2 => println!("its 2"),
+        3 => println!("its 3"),
+        _ => println!("its something else")
+    }
+}
+```
+
+Match will be checked by the compiler, so if a new possibility is added, you will be notified when this occurs
+
+In contrast, else..if is not checked by the compiler. If a new possibility is added, your code may contain a bug
+
+Prefer using match over else..if when working with a single variable

+# Traits
+
+Traits define similar functionality for different types
+
+It can be used to standardize functionality across multiple different types.
+
+Standardization permits functions to operate on multiple different types. [ Code deduplication ]
+
+## Generic Functions
+
+Generic functions are functions that can operate on multiple different types.
+
+A function that can have a single parameter to operate on multiple different types.
+
+Trait is used as function parameter instead of data type. Function depends on existence of functions declared by trait.
+
+Efficient code. Automatically deduces the type of the parameter when new data type is used.
+
+3 types of Generic Syntaxes
+
+1. Using impl Trait. 
+   * Any type that implements a trait. Go with this when you have small number of traits and small number of parameters.
+    ```rust, ignore
+    fn function(param1: impl Trait1, param2: impl Trait2) {
+    // code
+    }
+    ```
+
+2. Usual
+   * A generic type `T` is constrained to implement a specific Trait `Trait1` and `U` is contrained to implement `Trait2`.
+   The function parameter must be of Type `T` and `U` and the function will only work if the parameters implement the traits.
+    
+   ```rust,ignore
+   fn function<T: Trait1, U: Trait2>(param1: T, param2: U){
+       // code
+   }
+   ```
+   * Generic type `T` (used to define the type of the parameter) then the trait that the type must implement.
+     In the function parameters we set `thing` to be of type `T`
+     and then we call the `move_to` method on `thing`.
+
+   ```rust, ignore
+    fn make_move<T: Move>(thing: T, x: i32, y: i32) {
+    thing.move_to(x, y);
+    }
+    ```                                                                                                                                                                                                                                                                                                                                                                                                                                                         
+
+3. Usual using Where keyword [most preferred]
+   * A generic type `T` and `U` are used as parameters and then we use the `where` keyword to specify the constraints.
+       
+   ```rust, ignore
+   fn function<T, U>(param1: T, param2: U)
+       where
+           T: Trait1 + Trait2,
+           U: Trait3 + Trait4
+   {
+   // code
+   }
+   ```
+
+    ```rust, ignore
+    fn make_move<T>(thing: T, x: i32, y: i32)
+        where T: Move
+    {
+        thing.move_to(x, y);
+    }
+    ```
