Lifetimes / Return references

📄️ Overview

References in arguments (such as fn f(a &mut Bar)) is already supported long ago,

📄️ Types with lifetimes

We can have function like fn f(foo: &'a Foo) -> Bar,

📄️ Return references

Suppose we have the following function:

📄️ Multi borrows

In this page, we discuss a limitation of types with lifetimes because of combination of Rust and Dart.

📄️ Alternatives

In addition to directly using the feature, sometimes the following alternative approaches are also helpful.
