Struct FakeRenderer 

pub struct FakeRenderer { /* private fields */ }

A seeded additive synth behind the Renderer trait.

Implementations

impl FakeRenderer

pub fn new(synth: Synth, seed: u64) -> Self

Builds a renderer that claims to be synth. Two renderers with one seed give bit-identical renders in the same order.

pub fn with_patch(self, patch: FakePatch) -> Self

Plays patch whatever state a job holds, as a plug-in that loads any preset of its synth. The saved state is still the loaded one.

pub fn with_log(self, log: FakeLog) -> Self

Records each step it plays in log.

pub fn with_fault(self, at: u64, fault: Fault) -> Self

Injects fault into the render with index at, counted from 0.

pub fn renders(&self) -> u64

Returns how many renders were asked for, failed ones included.

Trait Implementations

impl Clone for FakeRenderer

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FakeRenderer

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

Formats the value using the given formatter.

impl Renderer for FakeRenderer

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 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.

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

Returns the state the plug-in saves now.
