Does Rust have a function to find the kth smallest element in an array or a segment of an array?
(Similar to std::nth_element in C++)

There is a much better approach to finding Kth smallest element, which relies on median-of-medians algorithm. Basically any partition algorithm would be good enough on average, but median-of-medians comes with the proof of worst-case O(N) time for finding the median.
Finding the kth smallest element in an array with sorting To execute this, We first sort the array then access its k-1th index, which contains the kth smallest element of the array. K'th smallest element is 45. The time complexity of this method is O(N*logN) because of the sorting algorithm used in it.
Yes (since rust 1.49)

I don't think there is such a function in std.
However, you can use the crate order_stat, which offers a kth function.
