 Hi again, in this lesson, we're going to talk about how to define a vector in Rust programming language. As we know, vector is a dynamic array. Vector is implemented inside standard library of Rust programming language. You should also notice that elements of vector are stored on the heap. And let's try now to create a vector. Let's go to the website play.rustlang.org And let's create some vector. We can create a vector with back exclamation and exclamation mark macro. And inside brackets we'll put few elements that our vector will contain. And let's save our vector. Let's save our vector to some variable. Let's call our variable myVector. Let's say let myVector equals vector with elements 1, 2, 3, 4 and 5. That's all for now. Now in this lesson we've created myVector and in some next video we will work a little bit with vectors. See you in next lesson. Bye.
