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.
