Rust Programming | Methods | Introduction

Introduction

In this lab, the usage of methods in Rust is demonstrated.

Note: If the lab does not specify a file name, you can use any file name you want. For example, you can use main.rs, compile and run it with rustc main.rs && ./main.

Methods

Methods are annotated similarly to functions:

struct Owner(i32); impl Owner { // Annotate lifetimes as in a standalone function. fn add_one<'a>(&'a mut self) { self.0 += 1; } fn print<'a>(&'a self) { println!("`print`: {}", self.0); } } fn main() { let mut owner = Owner(18); owner.add_one(); owner.print(); }
