Module host

Traits§

clear_host_call_bridge: Remove the current thread’s bridge. Idempotent.
dispatch_host_call_bridge: Dispatch (capability, operation, params) to the currently-installed HostCallBridge, if any. Some(Ok(_)) means the bridge handled the call; Some(Err(_)) means it tried but raised; None means there is no bridge or the bridge declined this op (returned Ok(None)).
dispatch_mock_hostlib_call: Dispatch a hostlib builtin through the same scoped mock registry used by host_call.
register_callable_host_operation
register_mockable_host_operation
register_scoped_mockable_host_operation: Register a mock-validation declaration scoped to the current test thread.
set_host_call_bridge: Install a bridge for the current thread. The bridge is consulted on every host_call after mock matching but before the built-in match arms, so embedders can override anything they like (and equally punt on anything they don’t, by returning Ok(None)).
