rustHow do I use a variable from another file in Rust?

Variables from another file can be used in Rust by importing the file containing the variable. This can be done using the use keyword.

// file1.rs
pub fn foo() {
    println!("foo");
}

// file2.rs
use file1;

fn main() {
    file1::foo();
}

Output example

foo

The use keyword imports the file containing the variable, allowing it to be used in the current file. The example above imports file1 into file2, allowing the foo function to be called.

• use keyword: imports the file containing the variable
• file1: the file containing the variable
• file2: the file using the variable
• foo: the variable being used
