Struct EdgeDesc 

pub struct EdgeDesc {
    pub from: String,
    pub to: String,
    pub label: Option<String>,
    pub style: Option<String>,
}

One directed edge between two node ids.

label and style are caller metadata carried through untouched. Same extensibility class as NodeDesc: plain + Default + FRU.

Fields

from: String

Source node id.

to: String

Target node id.

label: Option<String>

Optional display label (v1 renderers place it at the midpoint).

style: Option<String>

Optional style hint (opaque to layout).

Implementations

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

Attach a display label (builder style).

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