Module: Tempest::WarningFilter

Defined in:
lib/tempest/warning_filter.rb

Overview

Silences the Ruby 4.x experimental warning fired by ‘IO::Buffer`. The warning originates in `<internal:io>` but surfaces through async-dns / `resolv.rb` on the Jetstream WebSocket connect path, and the user cannot act on it. Other warnings, including unrelated `IO::Buffer` references, are forwarded to the original `Warning.warn` so genuine signals still reach stderr.
