5603ee7b - Change component/instance maps to `PrimaryMap` (#10916)

Tue, 03 Jun 2025 22:11:29 +0000

Change component/instance maps to `PrimaryMap` (#10916)* Change component/instance maps to `PrimaryMap`This switches to using typed keys for these maps to be more idiomaticwith the rest of Wasmtime and this has the additional benefit ofcompressing indices to 32-bits instead of the previouspointer-sized-bits.* Fix an unused import List of files: /wasmtime-44.0.1/crates/c-api/include/wasmtime/component/instance.h

8fb9d189 - Remove `Stored` usage from `wasmtime::component::Instance` (#10913)

Tue, 03 Jun 2025 20:21:59 +0000

Remove `Stored` usage from `wasmtime::component::Instance` (#10913)* Remove mutability required on a number of component methodsPowered by previous refactorings it's possible to just take`&StoreOpaque` in these locations.* Move core instance map into `ComponentInstance`This commit moves the mapping from a `RuntimeInstanceIndex` to a`wasmtime::Instance` from `wasmtime::component::InstanceData` into theinternal `ComponentInstance` structure. This is done in preparation toremove `InstanceData` eventually.* Move `Component` to live in `ComponentInstance`Previously this lived in `InstanceData` but that's just a historicalartifact of the old `wasmtime` and `wasmtime-runtime` split. Nowadaysit's possible to store `Component` directly to further move informationout of `InstanceData`.* Move `InstanceData::imports` to `ComponentInstance`More preparation for the removal of `InstanceData` entirely.* Move lookup functions from `InstanceData` to `ComponentInstance`More prep for the removal of `InstanceData`.* Reduce some more reliance on `InstanceState`Just removing it from some type signatures to make future removaleasier.* Remove an unused result from a helper functionNo caller needs it, so go ahead and remove it.* Make `ComponentInstance::imports` privateThis moves some methods around and documents preexisting `unsafe`contracts to get this field private and prevent external access to it.* Remove `InstanceData` from `Instantiator`.Use `OwnedComponentInstance` instead.* Remove `InstanceData`, refactor `Instance`This commit refactors the representation of `component::Instance` to bepurely index-based to data already within a store. This makes creationof an `Instance` free compared to before where auxiliary data needed tobe created. Note that this doesn't actually change storage within a`Store` as instances are still there, it's just that now the storagelives in a non-`Stored`-related location.
