refactor(actor): finish the Ffi→Wasm guest sdk rename by iamacoffeepot · Pull Request #2091 · iamacoffeepot/aether

iamacoffeepot · 2026-06-20T07:40:05Z

Closes #2090.

Summary

Finishes the Ffi→Wasm guest-SDK rename that #2089 began. #2089 moved the headline guest-facing types to Wasm* but left a tail of Ffi-named symbols and the ffi/ module itself, leaving Wasm* types living in a module whose own header documented ffi as a deliberately generic-over-hosts name. This commits to the wasm framing — wasm32 is the only host — and moves the remaining guest-SDK surface to Wasm:

ErasedFfiActor → ErasedWasmActor (the object-safe boxed dual of WasmActor; public, re-exported, and emitted by the #[actor] macro).
ComponentHostFfiExt → ComponentHostWasmExt, TcpFfiExt → TcpWasmExt — keeping the existing wasm-vs-native transport axis the *NativeExt duals already use.
Module aether-actor/src/ffi/ → src/wasm/ (pub mod ffi → pub mod wasm), with every crate::ffi:: / aether_actor::ffi:: path updated across aether-actor, aether-capabilities, and aether-substrate. The wasm/mod.rs header is rewritten to present-tense wasm framing.
Dead FfiTransport doc comments removed (the ZST was deleted in issue 665).
Trybuild UI fixtures *_ffi.rs (+ .stderr) renamed to *_wasm.rs.

The literal foreign-function boundary is kept as-is: wasm/raw.rs's extern "C" imports, the _p32 ABI suffix, the "Raw FFI boundary" comments, and the on-the-wire ABI symbol names (receive_p32, init, aether.kinds.inputs, aether.namespace) — that boundary genuinely is FFI and is an on-the-wire contract the substrate's wasm runtime expects. No behavior change, no wire-format change.

Test plan

Pure mechanical rename, validated by the existing suite — cargo nextest run --workspace (2187 passed), cargo clippy --workspace --all-targets -- -D warnings, cargo doc --workspace --no-deps, the wasm32 component cross-builds, and the trybuild UI suite (whose .stderr golden files embed the renamed fixture filenames). Full scripts/preflight.sh green.

/implement — agent execution of scoped issue #2090.

Renames ErasedFfiActor → ErasedWasmActor, ComponentHostFfiExt → ComponentHostWasmExt, TcpFfiExt → TcpWasmExt, and moves the aether-actor/src/ffi/ module to src/wasm/. All crate::ffi:: and aether_actor::ffi:: paths update to wasm::. The six *_ffi.rs trybuild fixtures (+ .stderr siblings) rename to *_wasm.rs. ADR/guide mentions of ErasedFfiActor and the old module path update. Kept intact: the extern "C" imports in wasm/raw.rs, the _p32 ABI suffix, "Raw FFI boundary" comments, and the on-the-wire ABI symbol names (receive_p32, init, aether.kinds.inputs, aether.namespace). Closes #2090. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
