rustWeak pointer example in Rust
Weak pointers in Rust are used to access data without taking ownership of it. They are useful when you need to access data without preventing it from being dropped. A weak pointer is declared using the Weak
type from the std::rc
module. Here is an example of declaring a weak pointer:
use std::rc::Weak;
let weak_ptr: Weak<i32> = Weak::new();
The weak pointer is declared as a Weak<i32>
type, which means it points to an i32
type. The Weak::new()
function is used to create a new weak pointer.
Output example:
No output is produced.
Explanation
The use std::rc::Weak
statement imports the Weak
type from the std::rc
module. This type is used to declare a weak pointer. The Weak::new()
function is used to create a new weak pointer.
