Struct DebugVisualizer 

pub struct DebugVisualizer { /* private fields */ }

Debug visualizer that renders real plot documents to disk.

Every create_* / plot_* method renders the supplied data into a real document (a genuine SVG/HTML/JSON file with axes, points and colour-mapped cells derived from the caller’s numbers), writes it under VisualizationConfig::output_directory and returns that file’s path.

Formats this crate cannot encode without an optional raster backend (ImageFormat::PNG, PDF, LaTeX, MP4, GIF, WebM) are rejected with a structured error naming the missing encoder — they are never written out as SVG bytes under a misleading extension.

Implementations

impl DebugVisualizer

pub fn new(config: VisualizationConfig) -> Self

pub fn with_default_config() -> Self

pub fn config(&self) -> &VisualizationConfig

The configuration this visualizer renders with.

pub fn create_line_plot(&mut self, data: &PlotData) -> Result<String>

Render a line plot and return the path of the file written.

pub fn create_heatmap(&mut self, data: &HeatmapData) -> Result<String>

Render a heatmap and return the path of the file written.

pub fn create_histogram(&mut self, data: &HistogramData) -> Result<String>

Render a histogram and return the path of the file written.

pub fn plot_tensor_distribution( &mut self, name: &str, values: &[f64], bins: usize, ) -> Result<String>

Plot tensor distribution

pub fn plot_training_metrics( &mut self, steps: &[f64], losses: &[f64], accuracies: Option<&[f64]>, ) -> Result<String>

Plot training metrics

pub fn plot_gradient_flow( &mut self, layer_name: &str, steps: &[f64], gradient_norms: &[f64], ) -> Result<String>

Plot gradient flow

pub fn plot_tensor_heatmap( &mut self, name: &str, values: &[Vec<f64>], ) -> Result<String>

Plot tensor heatmap

pub fn plot_activation_patterns( &mut self, layer_name: &str, inputs: &[f64], outputs: &[f64], ) -> Result<String>

Plot activation patterns

pub fn get_plot_names(&self) -> Vec<String>

Names of the plots this visualizer has actually rendered, in creation order.

Empty until something has been plotted — it is not a catalogue of what the visualizer could draw.

pub fn get_plot(&self, name: &str) -> Option<&RenderedPlot>

Look up a rendered plot by title.

pub fn create_dashboard(&mut self, plot_names: &[String]) -> Result<String>

Build a dashboard page embedding the named plots.

SVG/HTML renderings are inlined verbatim; a JSON rendering is linked by path (there is nothing to inline). Unknown names are rejected with a structured error listing what has actually been rendered, rather than emitting an empty card that looks like a plot.

pub fn export_plot_data( &self, plot_name: &str, export_path: &Path, ) -> Result<()>

Export a rendered plot’s source data as JSON to export_path.

Errors when plot_name has not been rendered — the previous version wrote the literal string "Plot data for: <name>", which contained no plot data at all and succeeded for names that never existed.

pub fn save_to_file(&self, filename: &str) -> Result<()>

Write the most recently rendered plot document to output_directory/filename.

Errors when nothing has been rendered yet, instead of writing the literal placeholder text the previous implementation emitted.

Trait Implementations

impl Debug for DebugVisualizer

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

Formats the value using the given formatter.
