Status: Courses Tags: Rust

1. Functions are defined like this below

   #![allow(unused)]
   fn main() {
   // Simple increment function
   fn function1(val: i32) -> i32 {
     newval = val + 1;
   }
   // Function with mutable arguments
   fn function1( mut val: i32) -> i32 {
     val = val + 1;
   }
   }
