Essential Macros ​

Unlike other programming languages, macros aren't frowned upon in Rust, in fact they are often the clearest way (and sometimes the only way) to access many standard library implementations.

vec! ​

Create a vector

let number_list = vec![5, 10, 20, 40, 80];

let number_list = vec![5, 10, 20, 40, 80];

println! ​

Print to Stdout using format specifiers

println!("Your list is {:?}", number_list);

println!("Your list is {:?}", number_list);

Add log::info! macros...
