# Thin cdylib wrapper around libdatadog's `libdd-profiling-heap-gotter` crate
# (published on crates.io).
#
# Why this crate exists (rather than consuming the upstream crate directly):
#   * Building our own cdylib lets us pick a clean `[lib] name` and so sidestep
#     libdatadog's repo-wide `liblib*.so` double-prefix convention: the output
#     is simply `libdd_heap_gotter.so`.
#   * It lets us expose a stable, ddtrace-owned C ABI (`ddtrace_heap_gotter_*`)
#     over the upstream crate's pure-Rust API, so the Python ctypes activator
#     links against fixed, unmangled symbol names and gets a plain `bool`.
