Description
🚀 Feature Proposal
We need a magic comment to define where is the actual user code to submit.
Motivation
I am playing with rust. The code structure is as follow.
pub struct Solution; impl Solution { pub fn two_sum(nums: Vec<i32>, target: i32) -> Vec<i32> { // ... } }
look at the first line(Line 9).
I will get an error in vs code without that line.
And I will get an error if I submit code with that line.
✘ Compile Error
✘ 0/0 cases passed (N/A)
✘ Error: Line 54, Char 1: the name `Solution` is defined multiple times (solution.rs)
✘ Error: Line 54, Char 1: the name `Solution` is defined multiple times (solution.rs)
|
9 | pub struct Solution {}
| ------------------- previous definition of the type `Solution` here
...
54 | struct Solution;
| ^^^^^^^^^^^^^^^^ `Solution` redefined here
|
= note: `Solution` must be defined only once in the type namespace of this module
The Line 54 is at LeetCode test side.
It is better to define which is the actual user code to submit and which is not.
For example:
pub struct Solution; // @lc user code start impl Solution { pub fn two_sum(nums: Vec<i32>, target: i32) -> Vec<i32> { unimplemented!() } } // @lc user code end #[cfg(test)] mod tests { use super::Solution; #[test] fn it_works() { assert_eq!(vec![1, 2], Solution::two_sum(vec![3, 2, 4], 6)); } }
# @lc user code start class Solution: def twoSum(self, nums: List[int], target: int) -> List[int]: pass # @lc user code end if __name__ == '__main__': s = Solution() print s.twoSum([3, 2, 4], 6)
