Rust Functions Programs

In the Rust programming language, the functions are declared using the fn keyword. Its arguments are type annotated, just like variables, and, if the function returns a value, the return type must be specified after an arrow ->

Practice these Rust functions programs to learn the concept of user-defined functions in Rust language, these programs contain the solved code, outputs, and a detailed explanation of the statements, functions used in the Rust functions Programs.
