Course Plan

Course plan.

Week - 1:

1. Installation
2. Introduction to cargo
3. Introduction to Rust Syntax:
   • Variables: let, mut
   • Functions: fn
   • String, str, format!, println!
   • Arrays: Vec, slice
   • HashMap (or Dictionary): HashMap
   • Ownership, Borrowing
   • Control Flow: if, if let, match
   • Loops: loop, while, while let, for, iterators

Homeworks:

1. Write fn hello(name:&str) -> String
   • will return: "Hello -name-!"
2. Write fn make_it_double(num:i32) -> i32
   • will return: 4 when given 2
3. Write fn multiply_pi(num:f32) -> f32
   • will multiply the num with Pi(π) and return the result.

Week - 2:

1. Introduction to:
   • Enum
   • Result
   • Option
   • Struct
   • Traits
   • Macro

Homeworks:

1. Write fn to_letter_grade(num:u8) -> String
   • will return "AA" for 100, "BA" for 89 etc.
2. Write fn log(level:LogLevel, msg:&str) -> String
   • LogLevel is an enum. Prints logs with level tag: [WARN]: This is warning log.
3. Write Person {name:String, age: u8, gender: Gender}
   • Gender is an enum. Also implement Display trait for Person with format: {name}({age}) ex: Emin(24).
4. Write display!(Person, "{}({})", name, gender)
   • This macro will implement Display trait for Person with format you provide.

Week - 3:

1. Crates, Tests
   • Crates: use, mod, pub mod, create your own crate
   • Usage of an example crate: serde
   • Writing Tests

Homeworks:

1. Make Person { name:String, age:u8, gender:Gender::Male } struct transformable to JSON string with serde & serde_json crate:
   • Example: {"name":"Emin","age":24,"gender":"Male"}
2. Write 3 test cases for first task.
3. Write jsonified output of the Person struct to person.json file.
   • Writing to a file examples: https://doc.rust-lang.org/std/fs/struct.File.html

Week - 4:

1. Closure
2. Iterator
   • filter
   • map
   • nth
   • count
   • enumerate
   • Fibonacci series with Iterator trait
3. Generics
4. Lifetimes

Homeworks:

1. Filter even numbers on a list
2. Multiply all numbers with 2 on a list
3. Implement an iterator which implements this algorithm: f(n) = f(n-1) * f(n-2) and n > 0

Week - 5:

1. Thread, Mutex, Atomic, Channel
   • Fearless Concurrency
   • thread
   • thread w/ mutex
   • thread w/ atomic
   • thread w/ channel

Homeworks:

1. Calculate nth prime number with threads.
   • Find every given prime number on an array &[u32] with spawning a thread for each of it, and send the result with std::sync::mpsc::Sender.

Week - 6:

1. Introduction to asynchronous programming:
   • async-std. async, Future
   • Example: async TCP server

Homeworks:

1. Write tcp chat server with async-std
   • Send each message to other connections.
   • Use Arc<Mutex<>> to share "user list" between the tasks.
   • Use 22222 port to make us test it easily.
