Data Types

• bool: Represents a boolean value (true or false)
• char: Represents a single character
• String: Owned string
• &str: String slice
• i8, i16, i32, i64: Signed integers with different bit sizes
• u8, u16, u32, u64: Unsigned integers with different bit sizes
• usize : Unsigned integer. Same number of bits as the platform's pointer type
• isize : Signed integer. Same number of bits as the platform's pointer type
• f32, f64: Floating point numbers with different precision
• arrays: Fixed-size collection of elements of the same type

let arr: [i32; 4] = [1, 2, 3, 4];

• tuples: Collection of elements of different types with a fixed size

let tup: (i32, f64, bool) = (500, 6.4, true);

• HashMap: s a data structure that implements an associative array or dictionary. It is an abstract data type that maps keys to values.

use std::collections::HashMap;

let solar_distance = HashMap::from([
    ("Mercury", 0.4),
    ("Venus", 0.7),
    ("Earth", 1.0),
    ("Mars", 1.5), 
]);
