Struct LayoutOpts 

pub struct LayoutOpts {
    pub algorithm: Option<LayoutAlgorithm>,
    pub direction: Option<LayoutDirection>,
    pub edge_routing: Option<EdgeRouting>,
    pub node_spacing: Option<f64>,
    pub layer_spacing: Option<f64>,
}

Layout for DepictSpec::ReactionScheme.

Backend-agnostic knobs — hosts map these onto ELK, Dagre, or another engine. Defaults when omitted: LayoutDirection::Right, EdgeRouting::Polyline, LayoutAlgorithm::Layered. Individual EdgeNodes may override Self::edge_routing.

Spacing (px, document space) controls packing tightness:

• Self::node_spacing — gap between nodes in the same layer (default ~20)
• Self::layer_spacing — gap between reactant/product layers (default ~0)

Fields

algorithm: Option<LayoutAlgorithm>

Placement algorithm (layered / radial / force / stress).

direction: Option<LayoutDirection>

Flow axis (right / left / up / down).

edge_routing: Option<EdgeRouting>

Shaft style (polyline / orthogonal / splines).

node_spacing: Option<f64>

Within-layer node gap (px). Smaller → tighter pack.

layer_spacing: Option<f64>

Between-layer gap along the flow axis (px). Smaller → tighter pack.

Implementations

impl LayoutOpts

pub const DEFAULT_NODE_SPACING: f64 = 20.0

Default within-layer gap for reaction schemes (px).

pub const DEFAULT_LAYER_SPACING: f64 = 0.0

Default between-layer gap for reaction schemes (px).

Trait Implementations

impl Clone for LayoutOpts

fn clone(&self) -> LayoutOpts

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutOpts

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

Formats the value using the given formatter.

impl Default for LayoutOpts

fn default() -> LayoutOpts

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LayoutOpts

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LayoutOpts

fn eq(&self, other: &LayoutOpts) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for LayoutOpts

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
