rustHow to create a subslice from a Rust slice?
Creating a subslice from a Rust slice is a simple process. The &[T] type provides the slice method which takes two indices and returns a subslice of the original slice.
let v = [1, 2, 3, 4, 5];
let s = &v[1..3];
println!("{:?}", s);
Output example
[2, 3]
The code above creates a subslice s from the original slice v by passing two indices 1 and 3 to the slice method. The output is a subslice containing elements from index 1 to index 3 (not including index 3).
Parts of the code:
let v = [1, 2, 3, 4, 5];: creates a slicevcontaining elements1,2,3,4, and5.let s = &v[1..3];: creates a subslicesfrom the original slicevby passing two indices1and3to theslicemethod.println!("{:?}", s);: prints the subslicesto the console.
