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.
