rust use namespace

Comment

// In Rust, there is no concept of "using" a namespace like in some other programming languages.
// Instead, Rust uses modules to organize and control the visibility of names (functions, types, constants, etc.).

// To bring items from a module into scope, you can use the use keyword.
// It allows you to create an alias for a module path, making it easier to refer to its contents.

// Here's an example of how to use the use keyword in Rust:

// Create an alias for the module path
use std::collections::HashMap;

fn main() {
    // Now we can directly use HashMap without specifying the full path
    let mut map = HashMap::new();
    map.insert(1, "one");
    map.insert(2, "two");

    // Accessing the HashMap's methods
    if let Some(value) = map.get(&1) {
        println!("Value: {}", value);
    }
}
