split a string into an array of substrings in rust

To split a string into an array of substrings in Rust, you can use the split method of the str type. Here is an example:

main.rs
let my_string = "hello,world,rust";
let my_array: Vec<&str> = my_string.split(',').collect();
94 chars
3 lines

In this example, my_string is the string that we want to split, and ',' is the delimiter we want to use for splitting. We then call the split method on the string, which returns an iterator of substrings. Finally, we use the collect method to collect the iterator into a Vec<&str>.

Note that the delimiter passed to the split method can be any character or substring that you want to use for splitting.
