I'm writing a generic function: pub fn sort_by_axis<T>(data: &mut Vec<T>, ind: usize) { } that sorts the given data by ind-th coordinate. How to constraint the type T to define that T[i] returns a Float type?

There is also another trait bound (T: Index<usize>) and a generic parameter for Index missing. Here a version of your code that compiles: use num_traits::Float; use std::ops::Index; pub fn sort_by_axis<T>(data: &mut Vec<T>, ind: usize) where <T as Index<usize>>::Output: Float, T: Index<usi…
