W0022: feedback clause ignores prior state

Generated from rellum-diagnostics/src/db.rs.

Explanation

A feedback clause that does not read the prior state value cannot accumulate from the previous tick. If it also ignores the triggering event payload, it produces the same value every time the clause fires.

Common causes

• writing on event => 1 when intending to increment
• forgetting to reference the state binding inside its feedback clause

Canonical fixes

• reference the prior state value when the clause should accumulate

Before:

on event => 1

After:

on event => count + 1

Code example

on event => 1
