pub trait NoteSink<N> {
// Required method
fn note(&mut self, note: N);
}Expand description
Receives the decisions a protocol narrates.
Separate from EffectSink, and deliberately. An effect is deferred: it describes something
the driver will do on the protocol’s behalf. A note describes something that has already
happened, at a point inside the handler — so it is recorded at the moment of the call, in the
handler’s own text, for the same reason crate::Store is not an effect either.
Nothing a protocol can observe reveals whether anything is listening, so no behaviour can depend on it: a run is identical whether or not it was read.

This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
