rustConst pointer example in Rust

A const pointer in Rust is a pointer that points to a value that cannot be changed. An example of a const pointer in Rust is shown below:

let x = 5;
let y = &x;
let z: &const i32 = y;

In this example, x is an i32 variable with the value 5. y is a pointer to x, and z is a const pointer to y.

Output example

No output is produced from this code.

Explanation

The let x = 5; statement creates an i32 variable x with the value 5. The let y = &x; statement creates a pointer y to x. The let z: &const i32 = y; statement creates a const pointer z to y.
