In Avro 1.12 official support for the
fixedtype was added for the logical typeuuid. avro-rs had a different interpretation of that and would rewrite it to abytestype.To remain compatible with the legacy implementation, avro-rs now supports
string,fixed, andbytes.bytesdoes not match spec, but does allow users to read already encoded data.This is a severe breaking change, although only for people who only use avro-rs (the legacy encoding did not, and still does not work with other languages).
I've also reworked
Schema::Decimalto use a similar setup asSchema::Uuidwhich saves aBoxand does not make the type bigger.
