- Best expression to push or append to Vec and return resulting Vec : r rust
The best expression to add an element to a vector and return the vector is the one in your third code block: { vec push(element); vec } or if you’re adding multiple elements either extend or extend_from_slice, e g : { vec extend(other_vec); vec } Unless of course you don’t care about performance in which case you can use concat
- Any efficient way of splitting vector? : r rust - Reddit
Hey guys is there any fast and efficient way of splitting vec into separate n vectors or arrays without blunt iteration and pushing values into each…
- vec! [] or Vec::new ()? : r rust - Reddit
I use vec![] for initialization from a literal list of elements or a pre-allocated repetition of a single value for its similarity to Rust's array initialization syntax I use Vec::new() for initializing a Vec without a predefined capacity I never use vec![] or Vec::with_capacity(0)
- How much faster are arrays that vecs and is my madcap scheme . . . - Reddit
a Vec<T> is 3 pointers long, no matter how many elements there are if you know in advance (at runtime) the number of elements you need, you can use Vec::with_capacity to reserve enough space up front - for large arrays, this essentially makes the malloc cost disappear, as the cost of the actual operation dominates the cost of malloc

- How do I iterate over a vector with a for in loop when item . . . - Reddit
It's a clever trick The flavor of ownership borrowing you use on the vector gets propagated to the items in a for loop If you iterate over an owned Vec you get owned T s A borrowed Vec gets you borrowed T s A mut Vec<T> gets you mut T s So, thanks to number 3, you can iterate over mut self heroes to get mut Hero references
