> The {{uuid}} base type ([THRIFT-5587|https://issues.apache.org/jira/browse/THRIFT-5587], 0.17.0) is not implemented for Erlang. [t_erl_generator.cc|https://github.com/apache/thrift/blob/master/compiler/cpp/src/thrift/generate/t_erl_generator.cc#L886] has no {{TYPE_UUID}} case in its type switches and fails generation, and {{lib/erl}} has no uuid in its protocol layer.
> {code}
> struct S { 1: uuid id }

> $ thrift --gen erl repro.thrift
> [FAILURE:generation:1] Error: compiler error: unsupported base type uuid
> {noformat}
> Filed so the gap is on record; the fix needs the library side too (read and write of the 16-byte value in the binary and compact protocols, and a representation, probably a 36-character binary like the other dynamic languages use). Reproduced on master at 3af0cfff1.
