Hang in custom Vec #148653
Description
I tried this code:
struct Array<T> {
data: Vec<T>
}
fn sum_arrays<T>(first: Array<T>) -> Array<T> {
let mut result = Array {data: first.data.clone()};
result.data.push(8);
result
}
struct Vec<T> {data: Vec<T> }
impl<T> Vec<T> {
pub fn push(mut self: &mut Self, object: &T) -> &mut Self {
self
}
}Command: timeout 30s rustc file.rs
It did not finish within 30 seconds.
