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, channel, render_envelope, name_for=default_name_resolver)

Convert the WAL slice this participant should see into model events.

render_envelope is provided by the channel's adapter so the view stays adapter-neutral. name_for resolves an agent_id to its human-facing Passport.name for views that want to label projection lines with the sender — built-in views that don't label simply ignore it.
