Collections

#description

Rust is a systems programming language that is designed to be safe, concurrent, and fast. Rust’s collections provide a way to store multiple values of the same type in a single data structure.

Some of the commonly used collections in Rust are:
  1. Vectors: Vectors are resizable arrays that can store multiple values of the same type. They are useful when you want to store an unknown number of items.
  1. Strings: Strings in Rust are UTF-8 encoded and they are implemented as a collection of bytes. Rust provides a lot of useful methods to work with strings.
  1. Hash Maps: A hash map stores a collection of key-value pairs, where each key must be unique. Hash maps are implemented using a hash table data structure which allows for fast lookups and insertions.
  1. Arrays: Arrays are fixed-size collections that can store elements of the same type. The size of an array is determined at compile-time.

Collections in Rust are statically typed, which means that the compiler checks the types of the values being stored in the collection. This helps to prevent runtime errors caused by type mismatches.

In addition, Rust’s collections are memory safe, meaning that they are protected against buffer overflows, null pointer dereferences, and other memory-related errors. This is achieved through Rust’s ownership and borrowing model, which controls access to the data stored in a collection.
