How to get Subset from a Set in Rust ?

Answer

To get a sub Set in Rust, you can use slicing on arrays or slices.

✐ Examples

1 Get Sub Set with Items

In this example,

We define an array or slice named my_set containing elements of a specific type.
We specify the range of indices to extract the sub Set.
We use array or slice slicing with the specified range to get the sub Set.

Rust Program

fn main() {
    // Define array with items
    let my_set = ["apple", "banana", "orange", "grape", "melon"];

    // Get sub Set with items
    let sub_set = &my_set[1..4];
    println!("Sub Set with items: {:?}", sub_set);
}

Output

Sub Set with items: ["banana", "orange", "grape"]

2 Get Sub Set from Empty Set

In this example,

We define an empty array or slice named my_set.
We attempt to get a sub Set from the empty array or slice, which results in an empty sub Set.

Rust Program

fn main() {
    // Define empty array or slice
    let my_set: [&str; 0] = [];

    // Get sub Set from empty array or slice
    let sub_set = &my_set[1..4];
    println!("Sub Set from empty array or slice: {:?}", sub_set);
}

Output

Sub Set from empty array or slice: []
