rustHow do I borrow a variable in Rust?
In Rust, variables can be borrowed using the & operator. This operator creates a reference to the variable, allowing it to be used without taking ownership of it.
For example:
let x = 5;
let y = &x;This code creates a reference y to the variable x, which has the value 5.
The parts of this code are:
- let x = 5;: This declares a variable- xwith the value- 5.
- let y = &x;: This creates a reference- yto the variable- x.
For more information, see the Rust Reference.
