[ruby-core:121217] [Ruby master Feature#19059] Introduce top level `module TimeoutError` for aggregating various timeout error classes.

Issue #19059 has been updated by ioquatix (Samuel Williams). Status changed from Assigned to Closed It is unlikely that Ruby will adopt this, so I am going to close it. ---------------------------------------- Feature #19059: Introduce top level `module TimeoutError` for aggregating various timeout error classes. https://bugs.ruby-lang.org/issues/19059#change-112158 * Author: ioquatix (Samuel Williams) * Status: Closed * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- This proposal was originally part of <https://bugs.ruby-lang.org/issues/18630> but was removed because we could not decide on the name. Introduce the following: ```ruby module TimeoutError end IO::TimeoutError.include(TimeoutError) Regexp::TimeoutError.include(TimeoutError) # Maybe? Timeout::Error.include(TimeoutError) ``` It may be easier for users. This was discussed before with the following conclusion: - Top level `TimeoutError` is available. - Using a module for a `TimeoutError` may not be consistent with other top level `class #{thing}Error`. -- https://bugs.ruby-lang.org/
