WASIPreview3ComponentHost class final

WASI 0.3 / Preview3 component host boundary.

This fixed-version wrapper keeps Preview3 adapter code on the async-aware component profile while host capability gaps remain explicitly reported.

Constructors

WASIPreview3ComponentHost({WASIComponentHost? componentHost, WASIPreview3CliHost? cliHost, WASIPreview3FilesystemHost? filesystemHost, List<String> args = const <String>[], Map<String, String> env = const <String, String>{}, String? initialCwd, List<int> stdinData = const <int>[], WASIPreview3CliOutputHandler? stdout, WASIPreview3CliOutputHandler? stderr})
Creates a Preview3 component host over componentHost or a new host.
