rustRust partial borrow example


Rust allows partial borrows of data structures, which allows you to borrow a part of a data structure without borrowing the entire structure. This can be useful when you want to access a part of a data structure without taking ownership of the entire structure.

Example code

let mut data = vec![1, 2, 3];
let first = &data[0];
let second = &data[1];

Output example

first = &1
second = &2

Code explanation

  • let mut data = vec![1, 2, 3];: This line creates a mutable vector containing the elements 1, 2, and 3.
  • let first = &data[0];: This line creates a reference to the first element of the vector, which is 1.
  • let second = &data[1];: This line creates a reference to the second element of the vector, which is 2.
