SyncContext

Understand request ownership, phases, and runtime limits. See the guide.

class zett_agent.sync_runtime.SyncContext(runtime, source)

Adapt async with to ordinary with without changing the yielded value.

One async task owns both __aenter__ and __aexit__. This matters for task groups and cancellation scopes that must be exited by their entering task. An exception from the synchronous with body is passed to __aexit__; its truthy return suppresses the exception just as async with would.

The supplied runtime remains caller-owned. This is a resource-lifecycle adapter, not an AgentRunContext and not a synchronous proxy for the yielded resource’s methods.

Examples

Open a resource and invoke one of its asynchronous methods:

with SyncRuntime() as runtime:
    with runtime.context(open_connection()) as connection:
        runtime.call(connection.send, "Hello")

Parameters:

• runtime (SyncRuntime)

• source (AbstractAsyncContextManager[_T])
