rust initialize empty array

To initialize an empty array in Rust, you can use the Vec type and the new method. Here's an example:

let my_array: Vec<i32> = Vec::new();

In this example, my_array is an empty Vec of type i32. You can replace i32 with any other desired data type.

Alternatively, you can also use the vec![] macro to initialize an empty array. Here's how you can do it:

let my_array: Vec<i32> = vec![];

Both of these methods will create an empty array that you can later populate with values using the push method.
