Rust Error Handling Cheatsheet - Result handling functions

Introduction to Rust error handling

Rust error handling is nice but obligatory. Which makes it sometimes plenty of code.

Functions return values of type Result that is "enumeration". In Rust enumeration means complex value that has alternatives and that alternative is shown with a tag.

Result is defined as Ok or Err. The definition is generic, and both alternatives have

type Set struct {
	list map[int]struct{} //empty structs occupy 0 memory
}

func (s *Set) Has(v int) bool {
	_, ok := s.list[v]
	return ok
}

Overview

This gist is based on the information available at golang/dep, only slightly more terse and annotated with a few notes and links primarily for my own personal benefit. It's public in case this information is helpful to anyone else as well.

I initially advocated Glide for my team and then, more recently, vndr. I've also taken the approach of exerting direct control over what goes into vendor/ in my Dockerfiles, and also work from isolated GOPATH environments on my system per project to ensure that dependencies are explicitly found under vendor/.

At the end of the day, vendoring (and committing vendor/) is about being in control of your dependencies and being able to achieve reproducible builds. While you can achieve this manually, things that are nice to have in a vendoring tool include:

NiFi Example: How to Put/Get to/from a DistributedCache

Left part: Put

Set values you'd like to cache to the content of a FlowFile. Then pass it to PutDistributedCache.

Right part: Get

You can enrich incoming FlowFiles by adding an attribute with a value fetched from DistributedCache.
