Introduction
In this lab, we have some Rust code that demonstrates the usage of lifetimes in structs. The code includes a struct called Borrowed
that holds a reference to an i32
, and the reference must outlive the struct itself. There is also a struct called NamedBorrowed
with two references to i32
, both of which must outlive the struct. Additionally, there is an enum called Either
that can either be an i32
or a reference to one, and the reference must outlive the enum. Finally, the code creates instances of these structs and enum, and prints their contents to showcase the usage of lifetimes in Rust.
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
.
