Struct DriverResult 

pub struct DriverResult<P>
where
    P: PluginExport,
{
    pub output: Vec<Vec<f32>>,
    pub sample_rate: f64,
    pub block_size: usize,
    pub total_frames: usize,
    pub meters: MeterReadings,
    pub output_events: Vec<Event>,
    pub block_snapshots: Vec<Vec<(u32, f64)>>,
    pub plugin: P,
}

Captured audio + metadata + plugin instance from a PluginDriver run.

Holds the post-run plugin instance (plugin: P) so post-run assertions can read params or custom state directly. As a side effect, DriverResult: !Send whenever P: !Send - which is true for plugins built via truce::plugin! (the generated Plugin alias is unsafe impl Send only conditionally on its inner Params type). Test code rarely cares; document if you hit it.

Fields

output: Vec<Vec<f32>>

Channel-major output: output[ch][frame]. Empty when CaptureSpec::audio == false.

sample_rate: f64

block_size: usize

total_frames: usize

meters: MeterReadings

Final-or-per-block meter readings.

output_events: Vec<Event>

Output events emitted by the plugin. Offsets are absolute (cumulative across blocks). Empty unless CaptureSpec::output_events.

block_snapshots: Vec<Vec<(u32, f64)>>

Per-block param snapshots (one Vec per block), each entry (param_id, plain_value). Empty unless CaptureSpec::block_snapshots.

plugin: P

Post-run plugin instance. Read params or custom state from here when writing assertions over the final state.
