State
Hello-world for #[derive(State)] — the per-instance non-numeric
data plumbing.
Source: examples/truce-example-state/.
Guide: chapter 11 → state.
#What it demonstrates
- The split between params (numeric atoms — automatable, host
knows about them) and state (anything else — strings, file
paths, view modes, nested structs — the framework round-trips
bytes on
snapshot_into/load_statebut the host never sees the shape). #[derive(State)]on aStateBinding-bound struct.- A custom egui editor that reads + writes the instance label.
- An audio-thread param (
Active: BoolParam) sitting alongside the state-only label.
