Rust, known for its focus on memory safety, performance, and concurrency, provides a rich set of data structures in its standard library, collectively known as "collections." These collections are essential for organizing and manipulating data efficiently in your applications. While Vec and HashMap are often the go-to choices for most general-purpose data storage, Rust offers a variety of other specialized collections, each with its own strengths and optimal use cases 2.

This blog post will guide you through Rust's most common collections, explaining their purpose, typical use cases, and providing practical code examples. We'll also touch upon how to use custom hashing algorithms for HashMap and HashSet.
