Asserts the maximum value that can be returned from `Vec::len` Currently, casting `Vec<i32>` to `Vec<u32>` takes O(1) time: ```rust // See <https://godbolt.org/z/hxq3hnYKG> for assembly output. pub fn cast(vec: Vec<i32>) -> Vec<u32> { vec.into_iter().map(|e| e as _).collect() } ``` But the generated assembly is not the same as the identity function, which prevents us from casting `Vec<Vec<i32>>` to `Vec<Vec<u32>>` within O(1) time: ```rust // See <https://godbolt.org/z/7n48bxd9f> for assembly output. pub fn cast(vec: Vec<Vec<i32>>) -> Vec<Vec<u32>> { vec.into_iter() .map(|e| e.into_iter().map(|e| e as _).collect()) .collect() } ``` This change tries to fix the problem. You can see the comparison here: <https://godbolt.org/z/jdManrKvx>. |
