How to push an item (struct type) from vector1 to vector2 in Rust? Can someone help me?
let mut vec1: Vec<Struct1> = vec![]; let item1 = Struct1 { id: 1, name: "AlgoQ".to_string() }; vec1.push(item1); let mut vec2: Vec<Struct1> = vec![]; vec2.push(&vec1[0]); vec1.pop(); Error:
error[E0308]: mismatched types --> src/test4.rs:17:15 | 17 | vec2.push(&vec1[0]); | ^^^^^^^^ | | | expected struct `Struct1`, found `&Struct1` | help: consider removing the borrow: `vec1[0]` Your item can't be at both place. You have to either
vec2.push(vec1.remove(0)); Here, as you also want to pop from the first vector, you may directly do
if let Some(item) = vec1.pop() { vec2.push(item); } But be careful that pop removes at the end, not at index 0 so your snippet is a little obscure regarding your exact intent.
vec2.push(vec1[0].clone()); Now, if you really want the item to be, conceptually, at two places, you may store references (ie &Struct1) or indexes in your second vec.
