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

• Vimcasts on vimgrep

• Uses native vim regexes (which are slightly different from the regexes used by grep, ack, ag, etc) so the patterns are the same as with vim's within-file search patterns.

You can do a normal within-file search first, then re-use the same pattern to

YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.

Processing realtime event stream with Apache Storm

Introduction

In this tutorial, we will explore Apache Storm and use it with Apache Kafka to develop a multi-stage event processing pipeline.

In an event processing pipeline, each stage is a purpose-built step that performs some real-time processing against upstream event streams for downstream analysis. This produces increasingly richer event streams, as data flows through the pipeline:
