rust empty vector

To create an empty vector in Rust, you can use the Vec::new() function. This function creates a new vector with no elements. Here's an example:

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

In this example, empty_vector is a new vector of type i32 that is empty. You can replace i32 with any other data type you need.

Alternatively, you can also use the vec![] macro to create an empty vector. Here's an example:

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

Both methods will create an empty vector in Rust.
