Return Value

ChartResult<void> — true on success; on failure, ChartResult::error() distinguishes ChartError::BadPath, ChartError::RenderFailure, ChartError::EncodeFailure, ChartError::PdfUnsupported, ChartError::InvalidInput, and ChartError::VectorUnsupported. Contextually converts to bool so if (!ChartExporter::save(...)) still compiles.

Parameters

Name	Description
chart	Chart to render and save.
path	Output file path; extension selects format if opts.format is default.
opts	Export options (quality, supersampling, PDF backend).
