WasmComponentInstance class final

Component-level runtime that instantiates embedded core modules.

Current scope:

  • Instantiates embedded core modules discovered in section 0x01.
  • Exposes direct core export invocation.
  • Exposes component export aliases decoded from section 0x03 for function/memory/table/global/tag exports.
  • Provides canonical ABI lowering/lifting wrappers over a selected memory.

Constructors

WasmComponentInstance.fromBytes(Uint8List componentBytes, {WasmImports imports = const WasmImports(), WasmFeatureSet features = const WasmFeatureSet(componentModel: true), bool bestEffortDecode = false})
factory
WasmComponentInstance.fromComponent(WasmComponent component, {WasmImports imports = const WasmImports(), WasmFeatureSet features = const WasmFeatureSet(componentModel: true)})
