Struct Edge 

pub struct Edge {

    pub id: Id,
    pub source: Id,
    pub target: Id,

}

An edge connecting two nodes.

Fields

id: Id

source: Id

target: Id

source_handle: Option<Id>

Optional id of a specific source crate::Handle on the source node.

target_handle: Option<Id>

Optional id of a specific target crate::Handle on the target node.

source_seat: Option<PortSeat>

Under AnchorMode::Seats: the seat this end is pinned to. None leaves the end to the solver, which is where every connection starts.

target_seat: Option<PortSeat>

See Edge::source_seat.

label: Option<String>

label_position: f64

Where the label sits along the edge, as a fraction of the curve (clamped to the drawable range). Seat-anchored edges honour it; the default is the midpoint.

weight: u8

Stroke emphasis, 1–3. Seat-anchored arrowheads scale with it, so a heavier edge carries a proportionate head. Styling the stroke itself stays in style/CSS.

kind: EdgeKind

animated: bool

Animated edges render a marching-dashes effect.

selected: bool

selectable: bool

marker_start: MarkerKind

marker_end: MarkerKind

class: Option<String>

Extra CSS classes for the edge group.

style: Option<String>

Extra inline CSS for the visible edge path (e.g. stroke: #f43f5e).

Implementations

impl Edge

pub fn new(source: impl Into<Id>, target: impl Into<Id>) -> Self

Create an edge from source to target with an autogenerated id.

pub fn id(self, id: impl Into<Id>) -> Self

pub fn label(self, label: impl Into<String>) -> Self

pub fn label_position(self, position: f64) -> Self

pub fn marker_end(self, marker: MarkerKind) -> Self

pub fn source_seat(self, seat: PortSeat) -> Self

Pin this edge’s source end to a seat (used under AnchorMode::Seats).

pub fn target_seat(self, seat: PortSeat) -> Self

Pin this edge’s target end to a seat (used under AnchorMode::Seats).

pub fn source_handle(self, id: impl Into<Id>) -> Self

pub fn target_handle(self, id: impl Into<Id>) -> Self
