ExportDiagram exports the diagram to the specified format.

func (*DiagramUseCase) ExportDiagramWithOptions 

func (uc *DiagramUseCase) ExportDiagramWithOptions(ctx context.Context, diagramID string, format entity.ExportFormat, options entity.RenderOptions) (io.Reader, error)

ExportDiagramWithOptions exports a stored diagram using typed D2 v0.9 options.

func (*DiagramUseCase) FormatSource 

func (uc *DiagramUseCase) FormatSource(ctx context.Context, content string) (string, error)

func (*DiagramUseCase) GetSource 

func (uc *DiagramUseCase) GetSource(ctx context.Context, diagramID string) (string, error)

GetSource returns the canonical source for a stored diagram.

func (*DiagramUseCase) RenderDiagram 

func (uc *DiagramUseCase) RenderDiagram(ctx context.Context, content string, format entity.ExportFormat, theme *entity.Theme) (io.Reader, error)

RenderDiagram renders D2 text into a diagram.

func (*DiagramUseCase) RenderDiagramWithOptions 

func (uc *DiagramUseCase) RenderDiagramWithOptions(ctx context.Context, content string, format entity.ExportFormat, options entity.RenderOptions) (io.Reader, error)

RenderDiagramWithOptions renders D2 text using the typed D2 v0.9 options.

func (*DiagramUseCase) UpdateSource 

func (uc *DiagramUseCase) UpdateSource(ctx context.Context, diagramID, content string) (*entity.DiagramValidationResult, error)

UpdateSource validates and atomically replaces a stored diagram's source.

func (*DiagramUseCase) ValidateDiagram 

func (uc *DiagramUseCase) ValidateDiagram(ctx context.Context, content, diagramID *string) (*entity.DiagramValidationResult, error)

ValidateDiagram validates raw source or the current source of a stored diagram.
