Defined in:
lib/axn/exceptions.rb

Overview

Raised at enqueue when an async argument cannot be serialized for background execution. Field-aware: names the offending field, its class, and how to fix it. The fix hint is delegated to the serialization layer (Axn::Internal::AsyncSerialization), resolved at message time so this stays a pure exception definition.

Instance Method Details

#message ⇒ Object

Same shape as UnserializableValue#message above, and through the same owners: @value is caller-supplied, so its class is named via Internal::RenderedClassName rather than @value.class, and @field is a DECLARED name — foreign bytes of its own — so it is rendered rather than joined to the rendered class name beside it.

The hint is normalized here too, at the join. It is another module's method choosing between three texts, and which text that is must not be able to decide whether this message composes — the ordinary reason #message renders every operand of a composition rather than the ones known today to need it.
