# --- Scalable topics (pulsar::st) examples ---------------------------------

# implementation (lib/st) does not exist yet, so the examples are COMPILED here
# for header/API verification but are NOT linked into executables (there are no
# symbols to link against). Building this OBJECT library on every build keeps the
# examples from bit-rotting while the API is reviewed.
#
# TODO(scalable-topics): once lib/st lands, replace this with one
# add_executable + target_link_libraries(... pulsarShared) per file, exactly like
# the samples above.
# The core samples are header-only previews of the pulsar::st API and build with
# no extra dependency.
