I am learning cargo (rust package manager). My code is working from console, but I can't apply dependency in VS code

My actions

1 Create project

cargo new hello_world

2 add rand library to the Cargo.toml

[package]
name = "hello_world"
version = "0.1.0"
edition = "2021"

[dependencies]
rand = "0.6.5"

3 I can build and run my project via console

cargo build
cargo run

Problem I am run code via VS code. I am clicking 'run' button and see the following. (I don't have errors if run without. rand = "0.6.5" )

[Running] cd "/Users/mascai/root_folder/dev/projects/08_rust/01_test/hello_world/src/" && rustc main.rs && "/Users/mascai/root_folder/dev/projects/08_rust/01_test/hello_world/src/"main
error[E0433]: failed to resolve: use of undeclared crate or module `rand`
 --> main.rs:2:13
  |
2 |     let r = rand::random::<i32>();
  |             ^^^^ use of undeclared crate or module `rand`

error: aborting due to previous error

For more information about this error, try `rustc --explain E0433`.

P.S:

I am using MacOS, rust-analyzer extension was installed

`rustc main.rs` ? How do you expect that rustc will recognize the dependencies that you had defined as a Cargo input ? – Ömer Erden May 07 '23 at 10:51
How to configure vs code to run cargo build and cargo run? – mascai May 07 '23 at 10:58

This is really strange. Why does rust-analyzer uses rustc and not cargo? Please post all `rust-analyzer` settings you have in vscode. – Chayim Friedman May 07 '23 at 15:56
