alexcrichton opened PR #3914 from less-lazy to main:
This commit removes the currently existing laziness-via-
OnceCellwhen
aModuleis created for creating aModuleMemoryImagesdata
structure. Processing of data is now already shifted to compile time for
the wasm module which means that creating aModuleMemoryImagesis
either cheap because the module is backed by a file on disk, it's a
singlewriteinto the kernel to a memfd, or it's cheap as it's not
supported. This should help make module instantiation time more
deterministic, even for the first instantiation of a module.<!--
