def debug=(value)
  @debug = value
end

.debug? ⇒ Boolean

When true, swallowed exceptions are reported to $stderr so a worker Ractor that later crashes on an unshareable value has a traceable cause. Default false (silent, the historical behaviour).

Returns:

  • (Boolean)

  defined?(@debug) ? @debug : false
end

.swallow(label) ⇒ Object

Swallow an exception raised by the block, optionally logging it when debug? is on. label identifies the call site (e.g. "freeze AR ivar Post@column_defaults"). Keep the label short — it's only for grepping. Returns the block's value on success, nil on rescued StandardError.
