servo_arc 0.3.0

A fork of std::sync::Arc with some extra functionality and without weak references

Fork of Arc for Servo. This has the following advantages over std::sync::Arc:

  • We don't waste storage on the weak reference count.
  • We don't do extra RMU operations to handle the possibility of weak references.
  • We can experiment with arena allocation (todo).
  • We can add methods to support our custom use cases 1.
  • We have support for dynamically-sized types (see from_header_and_iter).
  • We have support for thin arcs to unsized types (see ThinArc).
  • We have support for references to static data, which don't do any refcounting.
