🔀 Control Flow in Rust
Why Control Flow?
Control flow lets your programs make decisions and repeat actions. Rust gives you powerful, safe, and expressive tools for this!
❓ if & else
Use if
to run code based on a condition:
rust
Loading…
- Conditions must be a bool (no
if x = 5
mistakes!) - You can chain with
else if
🎯 match: Pattern Matching
match
lets you compare a value against patterns (like a supercharged switch):
rust
Loading…
- The
_
pattern is a catch-all (likedefault
) - Patterns can be values, ranges, or even destructured data
🔁 Loops: repeat things!
1. loop (infinite)
rust
Loading…
- Use
break
to exit,continue
to skip to the next iteration
2. while
rust
Loading…
3. for
rust

for
is the most common loop in Rust—safe, concise, and works with ranges or collections
🧠 Summary
- Use
if
/else
for decisions - Use
match
for powerful pattern matching - Use
loop
,while
, andfor
for repetition - Rust’s control flow is safe and expressive
🦀 Pro Tip: Rust’s compiler checks your patterns—no missing cases, no silent bugs!
