Bincode instead? #489

Open simbleau opened 4 months ago

simbleau commented 4 months ago

What's the reason for using bitcode instead of bincode, which is arguably more mature and has wider adoption in production scenarios?

Gotcha, so this is a docs issue then. The README still specifies that bitcode is used.

cBournhonesque commented 4 months ago

The main reason was that bitcode is way more performant and efficient than bincode. However it doesn't support serializing/deserializing directly from impl Read or impl Write so it was a bit tedious to maintain. You're right the readme should be updated

Another benefit was that bitcode used bitpacking to reduce the bandwidth (a bool would only take 1 bit) vs 1 bool takes 1 byte in bincode
