alexcrichton opened PR #4236 from lift-lower-split
to main
:
This commit splits the current
ComponentValue
trait into three
separate traits:
ComponentType
- contains size/align/typecheck information in
addition to the "lower" representation.
Lift
- only containslift
andload
Lower
- only containslower
andstore
When describing the original implementation of host functions to Nick he
immediately pointed out this superior solution to the traits involved
with Wasmtime's support for typed parameters/returns in exported and
imported functions. Instead of having dynamic errors at runtime for
things like "you can't lift aString
" that's instead a static
compile-time error now.While I was doing this split I also refactored the
ComponentParams
trait a bit to haveComponentType
as a supertrait instead of a subtype
which made its implementations a bit more compact. Additionally its impl
blocks were folded into the existing tuple impl blocks.<!--
