Experience in other languages has proven that isolating each task's heap from the others is a reliable strategy and one that is easy for programmers to reason about. Heap isolation has the additional benefit that garbage collection must only be done -per-heap. Rust never "stops the world" to garbage-collect memory. +per-heap. Rust never "stops the world" to reclaim memory. Complete isolation of heaps between tasks implies that any data transferred between tasks must be copied. While this is a fine and |
