impl TextMeasurer for RoutedTextMeasurer<'_>

fn measure(&self, text: &str, style: &TextStyle) -> TextMetrics

fn measure_svg_text_computed_length_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures SVG <tspan>.getComputedTextLength()-like widths (advance length along the baseline).

fn measure_svg_text_bbox_x(&self, text: &str, style: &TextStyle) -> (f64, f64)

Measures the horizontal extents of an SVG <text> element relative to its anchor x.

fn measure_svg_text_bbox_x_with_ascii_overhang( &self, text: &str, style: &TextStyle, ) -> (f64, f64)

Measures SVG <text>.getBBox() horizontal extents while including ASCII overhang.

fn measure_svg_title_bbox_x(&self, text: &str, style: &TextStyle) -> (f64, f64)

Measures the horizontal extents for Mermaid diagram titles rendered as a single <text> node (no whitespace-tokenized <tspan> runs).

fn measure_svg_simple_text_bbox_width_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures the bbox width for Mermaid drawSimpleText(...).getBBox().width-style probes (used by upstream calculateTextWidth).

fn measure_svg_raw_text_bbox_width_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures raw SVG <text>.getBBox().width for diagram renderers that append text directly.

fn measure_svg_raw_text_bbox_height_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures raw SVG <text>.getBBox().height for direct text content.

fn measure_svg_text_bounding_client_rect_width_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures the CSS pixel width returned by SVG <text>.getBoundingClientRect().width.

fn measure_svg_tspan_text_bbox_width_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures a <text> node whose visible rows are emitted as child <tspan> elements.

fn measure_svg_tspan_text_bbox_height_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures the bbox height of a <text> node whose visible rows are child <tspan> nodes.

fn measure_svg_create_text_bbox_y_offset_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures the getBBox().y offset of Mermaid’s createFormattedText(...) SVG label.

fn measure_svg_create_text_middle_bbox_y_offset_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures the same createFormattedText(...) bbox y offset after the outer Architecture label container applies inherited dominant-baseline: middle.

fn measure_svg_simple_text_bbox_width_for_wrap_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures simple SVG text for wrap decisions.

fn measure_mermaid_calculate_text_dimensions( &self, text: &str, style: &TextStyle, ) -> TextMetrics

Measures one SVG row using Mermaid’s body-attached calculateTextDimensions(...) probe.

fn measure_canvas_text_width_px(&self, text: &str, style: &TextStyle) -> f64

Measures Canvas2D measureText(...).width for canvas-backed layout engines.

fn measure_svg_simple_text_bbox_height_px( &self, text: &str, style: &TextStyle, ) -> f64

Measures the bbox height for Mermaid drawSimpleText(...).getBBox().height-style probes.

fn measure_wrapped( &self, text: &str, style: &TextStyle, max_width: Option<f64>, wrap_mode: WrapMode, ) -> TextMetrics

fn measure_wrapped_with_raw_width( &self, text: &str, style: &TextStyle, max_width: Option<f64>, wrap_mode: WrapMode, ) -> (TextMetrics, Option<f64>)

Measures wrapped text and (optionally) returns the unwrapped width for the same payload.
