Tyler Rockwood (Nov 21 2023 at 02:41): Tyler Rockwood (Nov 21 2023 at 02:41):Hello! I have a question on with_host_memory and with_stack_memory APIs. Does Wasmtime assume the memory returned from those APIs are 0 filled? I know mmap anonymous zero fills the memory, but I'm not sure if the runtime relies on that or not.
Alex Crichton (Nov 21 2023 at 02:54):Yes, any request for memory creation and memory growth assumes that the contents are zero-filled
Tyler Rockwood (Nov 21 2023 at 02:57):Thanks, that explains the behavior I'm seeing :)
