# Oilpan - C++ Garbage Collection Oilpan is an open-source garbage collection library for C++ in Chromium. Directory structure: - `public`: Users should depend on interfaces in the `gc` namespace exposed through this directory. - `test`: Test utilities that are needed to write unit tests using the garbage collection library. - `core`: The implementation of the garbage collection library. Blink may temporarily depend on concepts found in here until the public interface is complete. The library is currently under construction. The Blink-specific parts can be found in third_party/blink/renderer/platform/heap.
