rustHow to create box str in Rust

Creating a box str in Rust is a simple process. To do so, you need to use the Box::new() function. This function takes a value and returns a pointer to a newly allocated value on the heap.

let my_str = Box::new("Hello World!");

The code above creates a Box containing a &str with the value "Hello World!".

The code consists of the following parts:

• let: This is a keyword used to declare a variable.
• my_str: This is the name of the variable.
• Box::new(): This is a function that takes a value and returns a pointer to a newly allocated value on the heap.
• "Hello World!": This is the value that is passed to the Box::new() function.
