driver.
a2c5cb8 is described below
commit a2c5cb8d571dc0b967b469263ce236f977e11f4c
Author: Andrei Sekretenko <asekrete...@mesosphere.com>
AuthorDate: Tue Sep 15 18:20:44 2020 +0200
Consolidated protobuf construction by the JNI scheduler driver.
This patch converts the copy-pasted internals of numerous
`construct<>()` specializations for protobufs into a single
template.
