2: Invalid input WebAssembly code at offset 6284134: locals exceed maximum

It seems like my WASM files currently get rejected because there are too many locals being used. Is there a way I can configure wasmtime to use a larger limit?

Ah unfortunately we don't have a way to tune those limits at the moment, but it wouldn't be too too hard to add

right now there's a bunch of hardcoded constants in wasmparser/src/limits.rs

but we could relatively easily turn those into a struct which configures the Validator which we then plumb all the way up to a wasmtime::Config

I guess I'll look into writing that PR then. Thanks :D
