pub fn check_stream_interface(
name: &str,
version: &str,
contracts: Option<&WitContracts>,
level: &WitLevel,
) -> Result<(), RuntimeError>Expand description
Checks a runtime: driver artifact’s imports against the stream interface of the WIT level
this host serves.
Refuses a component importing any murmur:text/* instance, or any murmur:stream/* instance
other than exactly murmur:stream/events at the version level lists (for the served level,
WIT_STREAM_EVENTS_IFACE): the host serves neither, so the driver would fail to instantiate
on its first turn. The imports among those that do not fit level are refused with
RuntimeError::WitLevelMismatch; only when every one is at the level’s version of its
package, under an interface name that does not exist, is it
RuntimeError::DriverStreamInterfaceNotServed. contracts is what
murmur_artifact::extract_wit_contracts read out of the driver’s wasm; None, and a
component importing neither package, pass.
