Interleave 2 byte streams with default payload fallback when one stream is shorter than the other.
damascus stream0 stream1 default
with files:
echo -ne "AA" > /tmp/as
echo -ne "BBBB" > /tmp/bs
echo -ne "CC" > /tmp/default
cargo run --release /tmp/as /tmp/bs /tmp/default
# writes "AABBCCBB" to stdout
here payload size = 2 bytes
with unix named pipes:
mkfifo /tmp/fifo1
mkfifo /tmp/fifo2
head -c 1K < /dev/zero > /tmp/default
seq 10000000 > /tmp/fifo1 &
seq 10000000 > /tmp/fifo2 &
payload size = 1KB

Note: payload size (i.e. default size) massively impacts throughput:
| payload size | throughput |
|---|---|
| 2 bytes | ~50MiB/s |
| 32 bytes | 612MiB/s |
| 64 bytes | 1018MiB/s |
| 500 bytes | 1.25GiB/s |
| 1KB | 1.35GiB/s |
