autogen.beta.network.views.base.ViewPolicy #

Bases: Protocol

Per-participant projection.

Implementations must be deterministic functions of the input WAL slice — calling project twice with the same input must produce the same events.

name instance-attribute #

name

project async #

project(wal, *, participant_id, session, render_envelope)

Convert the WAL slice this participant should see into model events. render_envelope is provided by the session's adapter so the view stays adapter-neutral.
