alexcrichton opened PR #1352 from filter-more to master:

Added in #1329 it's now possible for multiple parameters to be non-wasm
parameters, so the previous param_types method is no longer suitable
for acquiring all wasm-related parameters, rather then FuncEnvironment
must be consulted. This removes usage of param_types() as a method
from the wasm translation and instead adds a custom method inline for
filtering the parameters based on is_wasm_parameter.

Can you comment on why this is mut and Mut? The ultimate function should be a non-mutating predicate.

Oh this is mostly just a Rust idioms thing where you idiomatically take FnMut since it's the most flexible. For brevity and simplicity though I've switched this to Fn, since FnMut wasn't actually needed.

It's is_wasm_parameter because it isn't counting the number of ArgumentPurpose::Normal parameters.

@sunfishcode, so the above is a default implementation that embedders are supposed to override?

Yeah, embedders can override it if they wish. We added this hook because Wasmtime specifically wishes to override it.
