Support ByteArray with UnliftedFFITypes
Motivation
I have a bunch of places in library where I pass a ByteArray
to a C function through the FFI. For example:
foreign import ccall unsafe "rd_kafka_topic_partition_list_add"
rdKafkaTopicPartitionListAdd ::
Ptr TopicPartitionList
-> ByteArray#
-> Partition
-> IO (Ptr TopicPartition)
Every time I do this, I have to unwrap the ByteArray
to expose the ByteArray#
that I am trying to get at.
Proposal
When UnliftedFFITypes
is enabled, allow ByteArray
as an argument type in FFI calls. This is possible now that ByteArray
has been moved to base
.
