I have been reading Rust and Go in parallel and I see subtle differences in how both these languages deal with dangling pointers and the problems it causes. For example, here is a version in Rust:
fn main() {
let reference_to_nothing = dangle();
}
fn dangle() -> &String {
let s = String::from("hello");
&s
}
The above would error out saying that in the function dangle
, s
goes out of scope and I cannot return a reference to it! But in Go, this seems to be sort of allowed?
How is such a thing handled in Go? Is it easy to create dangling pointers in Go? If so what measures do I have to control them?
