Function smartnoise_runtime::components::resize::create_sampling_indices

pub fn create_sampling_indices(
    k: i64, 
    n: i64, 
    enforce_constant_time: bool
) -> Result<Vec<usize>>

Accepts size of set (n) and size of desired subset(k) and returns a uniformly drawn set of indices from [1, …, n] of size k.

This function is used to create a set of indices that can be used across multiple steps for consistent subsetting.

Arguments

• k - The size of the desired subset
• n - The size of the set from which you want to subset

Return

A vector of indices representing the subset

Example

use smartnoise_runtime::components::resize::create_sampling_indices;
let subset_indices = create_sampling_indices(5, 10, false);
