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.
