rustlang_journey

This repository documents my journey into learning and mastering rustlang.

It includes:

• Variables,
• Data Types
• Functions
• Structs and Enum
• ownerships and other programming paradigm in rust

Variables and Immutability in rust

Variables are immutable by default in rust. Adding mut in front of your variable declaration makes it muttable.

Constants

They are values bound to a name and are not alllowed to change. They are immutable and mut is not allowed. The type & value must be initialize when declaring a variable.

Shadowing

Involves using the value of an initially declared variable to update the same variable. Shadowing is different from using mut becuase in it let's yoou change the variable type while maintaining the initial variable name

Data Types

Scalar types in rust includes:

• Integers: i8, i16, i32, i64, isize, u8, u16, u32, u64 & usize
• Float: f32 & f64
• Boolean: true & false
• Character

Compound types in rust

• Turples : used to group together number of different types
• Array: is another wy for storing colection of multiple values. All element in array in rust must have the same type, fixed length once declared.

Functions

block of reusable code

Control Flow

checking for conditions before executing a code
