Rust For Loops

This lesson is part of Rust · All levels

Summary

This lesson discusses the repetition of 'for' in Rust used to iterate data collection or range. Repetition for in Rust is the safest and most efficient way to avoid out-of-bounds index errors. The novice developer will learn to iterate the elements idiomatically.

Key points

The 'for in' iteration iterates every element in the data collection
The notation of the 'early' number range results in a semi-open range (final exclusive) (.akhir)
The notation 'beginning=end' includes the end-boundary of the range inclusive.
The '.rev() ' method can be used to reverse the order of the number range
