How to get Subset from a Set in Rust - Step by Step Examples
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: []
