rustRust null value example

Null values in Rust are represented by the Option enum. Option is an enum with two variants, Some and None. Some is used to wrap a value, while None is used to indicate the absence of a value.

Example code

let x: Option<i32> = None;

This code creates a variable x of type Option<i32> and assigns it the value None. This indicates that x does not have a value.
