Rust Data Structures

This lesson is part of Rust · All levels

Summary

This lesson provides an overview of the data structures available in Rust to group several values. Rust distinguishes static data structures in stacks such as arrays and tuple, as well as dynamic collections in heaps such as vectors and hash maps. Beginners are asked to identify when the right time to use each structure is.

Key points

Scalar data holds a single value, whereas composite data group multiple values
Arrays and tuple are allocated to stacks with fixed memory sizes
Collections such as Vector and HashMap are allocated to heaps with flexible capacity
The selection of the right data structure affects the performance and memory efficiency of the program
