I've never had great understanding of launchctl but the deprecation of the old commands with launchctl 2 (10.10) has been terrible as all resources only cover the old commands, and documentation for Apple utilities is generally disgracefully bad, with launchctl not dissembling.

Mad props to https://babodee.wordpress.com/2016/04/09/launchctl-2-0-syntax/ which contains most details

domains

Internally, launchd has several domains, but launchctl 1 would only ask for service names,

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
