Wasmtime GitHub notifications bot (Jun 28 2022 at 20:08):alexcrichton opened PR #4348 from error-reexport to main:
Currently I don't know how we can reasonably implement this. Given all
the signatures of how we call functions and how functions are called on
the host there's no real feasible way that I know of to hook these two
up "seamlessly". This means that a component which reexports an imported
function can't be run in Wasmtime.One of the main reasons for this is that when calling a component
function Wasmtime wants to lower arguments first and then have them
lifted when the host is called. With a reexport though there's not
actually anything to lower into so we'd sort of need something similar
to a table on the side or maybe a linear memory and that seems like it'd
get quite complicated quite quickly for not really all that much
benefit. As-such for now this simply returns a first-class error (rather
than the current panic) in situations like this.<!--
