initializing array rust

To initialize an array in Rust, you can use the following syntax:

let array = [value1, value2, value3];

In this syntax, array is the name of the array, and value1, value2, and value3 are the values you want to initialize the array with. The size of the array is determined by the number of values provided.

Alternatively, you can also use the vec! macro to initialize a dynamically-sized array (a Vec) in Rust. Here's an example:

let array = vec![value1, value2, value3];

In this case, array is a Vec that can grow or shrink in size as needed. The vec! macro automatically creates a Vec and initializes it with the provided values.

You can also initialize an array with a single value repeated multiple times using the array macro. Here's an example:

let array = [value; size];

In this syntax, value is the value you want to initialize the array with, and size is the number of elements in the array. All elements in the array will have the same value.

These are the basic ways to initialize arrays in Rust. Remember to replace value1, value2, and value3 with the actual values you want to use.
