How to raise custom exceptions in Ruby
July 18, 2022 ‐ 1 min read
You can get quite far with throwing generic exceptions, by just passing a string to raise.
raise 'There was a timeout'

All custom errors classes you define should inherit from StandardError or one of its subclasses.
class HttpTimeoutError < StandardError
end
raise HttpTimeoutError
