Macro array 

macro_rules! array {
    () => { ... };
    ($($val:expr),* $(,)?) => { ... };
}

Creates an Array containing the given values.

This macro provides a convenient way to create an Array with initial values, similar to the vec! macro for Vec.

Examples

// Create an empty array
let empty = array![];

// Create an array with values
let numbers = array![1, 2, 3, 4, 5];

// Trailing commas are allowed
let mixed = array![
    "hello",
    42,
    true,
];

Notes

• Values are automatically converted using .into(), so they must implement the appropriate Into trait for the array’s element type.
• The capacity is pre-allocated to match the number of elements when known at compile time.
