Understanding Data Types in Rust

Data Types in Rust

Rust has several built-in data types, which can be categorized into two main types: scalar and compound types.

• Scalar Types: These represent a single value.
  • i32: A 32-bit signed integer. Example: let age: i32 = 30;
  • f64: A 64-bit floating point number. Example: let height: f64 = 5.9;
  • char: A single character. Example: let letter: char = 'A';
  • bool: A boolean value, either true or false. Example: let is_student: bool = true;
• Compound Types: These can combine multiple values.
  • Tuple: A fixed-size collection of values of different types. Example: let person: (&str, i32) = ("Alice", 30);
  • Array: A collection of elements of the same type with a fixed length. Example: let numbers: [i32; 5] = [1, 2, 3, 4, 5];
