Rust While Loops

This lesson is part of Rust · All levels

Summary

This lesson reviews conditional repetition using the keyword 'while' in Rust. The code within the while block will be executed repeatedly during the value of the condition. Once the condition is evaluated to false, the repetition will be completed and the program continues the next instruction.

Key points

The 'while' iteration evaluates the condition before each iteration
It's perfectly suited for use when the number of iterations cannot be determined at the beginning.
Reduces the risk of endless repetitive errors compared to manual loops
It can be combined with the keywords 'break' and 'continue'
