Struct VitaRenderer 

pub struct VitaRenderer { /* private fields */ }

Plays single notes through the open engine in a Python process.

Implementations

impl VitaRenderer

pub fn start(python: &Path, script: &Path) -> Result<Self, RenderError>

Starts a renderer that runs script, tools/vita/render.py, with python.

Errors

Returns RenderError::Engine when the script does not run or names no vita version.

Trait Implementations

impl Debug for VitaRenderer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Renderer for VitaRenderer

fn identity(&self) -> HostIdentity

Returns what renders.

fn render(&mut self, job: &RenderJob) -> Result<Rendered, RenderError>

Renders one job.

fn render_init(&mut self, job: &RenderJob) -> Result<Rendered, RenderError>

Renders the job’s notes with the plug-in’s own init patch: the job’s state is not loaded. Only a renderer that has loaded no state yet holds the init patch, so the load check calls this first.

fn save_state(&mut self) -> Result<Vec<u8>, RenderError>

Returns the state the plug-in saves now.

fn last_state_load(&self) -> Option<Seconds>

Returns how long the state load of the last render took, when the backend measures it. A render of the init patch loads no state.
