Rust Arrays

This lesson is part of Rust · All levels

Summary

This lesson reviews an array in Rust that is a set of elements of the same type with a fixed length. Because it's stored in stacks, the array is very fast and efficient. The reader will learn to declare an array, access elements through an index, and understand the bound check.

Key points

The array has uniform types and fixed sizes known since compilation
The array type declaration is formatted '[Type; Number of Elements]'
The array index starts with a number of 0.
Out of bounds index access will trigger runtime panic for memory security
