v0.22.0 - 2023-01-16

Added

• Add missing TypedFunc::call_resumable API. (#605)
  • So far resumable calls were only available for the Func type.
    However, there was no technical reason why it was not implemented
    for TypedFunc so this mirrored API now exists.
  • This also cleans up rough edges with the Func::call_resumable API.

Changed

• Clean up the wasmi_core crate API. (#607, #608, #609)
  • This removes plenty of traits from the public interface of the crate
    which greatly simplifies the API surface for users.
  • The UntypedValue type gained some new methods to replace functionality
    that was provided in parts by the removed traits.
• The wasmi crate now follows the Wasmtime API a bit more closely. (#613)
  • StoreContext new methods:
    • fn engine(&self) -> &Engine
    • fn data(&self) -> &T
  • StoreContextMut new methods:
    • fn engine(&self) -> &Engine
    • fn data(&self) -> &T
    • fn data_mut(&mut self) -> &mut T
  • Renamed Store::state method to Store::data.
  • Renamed Store::state_mut method to Store::data_mut.
  • Renamed Store::into_state method to Store::into_data.

Internal

• The Store and Engine types are better decoupled from their generic parts. (#610, #611)
  • This might reduce binary bloat and may have positive effects on the performance.
    In fact we measured significant performance improvements on the Wasm target.
