- amqp-payload-conversionconstant
- default
- (make-parameter bitstring->blob)
The ampq egg uses bitstring to handle binary data internally, but in an attempt to avoid abstraction leakage message payloads returned by amqp-receive-message are converted to standard blobs. If you don't want this behaviour, set the parameter amqp-payload-conversion to either #f or a function that accepts a bitstring and returns the desired payload format.
