Rust for Rustaceans

4 Error Handling

For all but the simplest programs, you will have methods that can fail. In this chapter, we’ll look at different ways to represent, handle, and propagate those failures and the advantages and drawbacks of each. We’ll start by exploring different ways to represent errors, including enumeration and erasure, and then examine some special error cases that require a different representation technique. Next, we’ll look at various ways of handling errors and the future of error handling.

It’s worth noting that best practices for error handling in Rust are still an active topic of conversation, and at the time of writing, the ecosystem ...
