Struct LayoutOptions 

pub struct LayoutOptions {
    pub text_measurer: Arc<dyn TextMeasurer + Send + Sync>,
    pub math_renderer: Option<Arc<dyn MathRenderer + Send + Sync>>,
    pub viewport_width: f64,
    pub viewport_height: f64,
    pub use_manatee_layout: bool,
}

Fields

text_measurer: Arc<dyn TextMeasurer + Send + Sync>

math_renderer: Option<Arc<dyn MathRenderer + Send + Sync>>

Optional math renderer for $$...$$ style labels.

viewport_width: f64

viewport_height: f64

use_manatee_layout: bool

Enable experimental layout engines (e.g. Cytoscape COSE/FCoSE ports) for diagrams that currently use placeholder layouts in merman.

Implementations

impl LayoutOptions

pub fn headless_svg_defaults() -> Self

Returns layout defaults suitable for headless SVG rendering in UI integrations.

Compared to Default, this uses a Mermaid-like text measurer backed by vendored font metrics (instead of deterministic placeholder metrics).

pub fn with_text_measurer( self, measurer: Arc<dyn TextMeasurer + Send + Sync>, ) -> Self

pub fn with_math_renderer( self, renderer: Arc<dyn MathRenderer + Send + Sync>, ) -> Self

Trait Implementations

impl Clone for LayoutOptions

fn clone(&self) -> LayoutOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for LayoutOptions

fn default() -> Self

Returns the “default value” for a type.
