Learning Rust

Programs based on the official Rust Book 2.0

Summary

1. hello_world
   • Use println! macro
2. hello_cargo
   • Use cargo package manager
3. guessing_game
   • Use external crate(rand)
   • Defining a trait
   • Creating new variables with let
   • Creating new mutable variables with mut
   • Using associate(static) methods with ::
   • Type annotations
   • Variable shadowing
   • Handling results
   • Using loops
   • Using break
   • Using match
   • Using cmp
   • Using rand...
4. variables
   • Declaring immutable variables with let
   • Declaring mutable variables with mut
   • Declaring constants with const
   • Value and type shadowing
   • Differnce between the three types
5. data_types
   • Declaring scalar and compound data-types(tuple and arrays)
   • Declaring variables with types (& sometimes size)
   • Creating fixed length arrays
   • Accessing elements of compound data-types
6. functions
   • Creating functions using fn
     • with parameters and return types(appended after ->)
     • with explicit returns
     • with implicit returns
7. control_flow
   • Using if/else/else if
   • Using conditional as expressions
   • Creating and breaking loops
   • That break return the value of the following expression
   • Using while
   • Using for
   • Using .. to generate range
   • Using iter() method to iterate through an array
   • Using rev() method to reverse a range
8. f2c
   • Using function on strings
   • Dabble into iterators
   • Using if conditional
   • Creating functions with fn
9. fibonacci
   • Used recursive function
   • Alternative using iteration
   • Learned that Rust still doesn't support destructuring assignment
   • And also no sane way to use yield
   • The iterative alt. function has a bug!
10. christmas_song
    • More conditionals
    • Using .. operator for iteration
    • That {:?} is for debug purposes
