This will make it clear that it's deliberate

I assume that call returns a Result. If so, then and_then here seems useless and we can get away with a map?

I assume this is here only to be able to return this from the limiter and it is not possible to move the StoreLimits into the closure that limiter accepts. If so, it would be good to mention that here as a doc comment.

It would be nice to leave a note that this is only Some during the call into the runtime.

Can we preserve vertical alignment for this change?

It's a shame the reads require |

I get it now: memory_as_slice_mut removed for data_mut ( https://docs.wasmtime.dev/api/wasmtime/struct.Store.html#method.data_mut ). Yeah that's much nicer.
FYI: I see the dev release of the next version of wasmtime just dropped - looks like some module loading speedups just landed (not that I know what a veneer is...)

Looks like you'll have to bump the zstd on polkadot... |
