Rust uses the `?` operator to convert between error types which allows for users and libraries to hook in to the error before its returned.

There are a number of helper libraries that provide an extended type erased error type to attach a real stack trace to the error, such as `anyhow`. These helper libraries also provide ways to attach extra metadata to the error so you can do things like `returns_a_result().context("couldn't do it")?` so you can quickly annotate the error. The standard library is support for this through a `context.Value` like api on the Error trait. The std lib `Error` trait also has functions for find the cause of the error and traverse a collected chain of errors, very similar to go's `errors.Cause` api.

Rust also has a number of libraries for making specific error types like `thiserror` which can help generate error enums with the implementations required to carry backtraces, context and causes.
