📦 Rust Data Types

✨ Scalar Types

Scalar types represent a single value. There are four:

• i32, u64, etc. — Integers (signed & unsigned)
• f32, f64 — Floating-point numbers
• bool — true or false
• char — a single character like 'a', '🦀'

Rust will infer types if you don't specify them (when it makes sense):

🧱 Compound Types

Compound types can hold multiple values. Two big ones:

1. Tuples

Group different types together.

2. Arrays

Fixed-size lists of same-type values.

🧠 Type Annotations: When & Why?

Sometimes, Rust needs a little help figuring things out:

Be explicit when:

• You call .parse()
• You want clarity in your code
• You’re working with multiple number types

🎯 Summary

• Scalar types: i32, f64, bool, char
• Compound types: tuple, array
• Rust infers most types unless it gets confused
• Use type annotations when needed for clarity or to satisfy the compiler
