Struct Edge 

pub struct Edge {
    pub step: String,
    pub when: Option<Guard>,
}

A dependency edge into a step.

In JSON, a plain string ("verify") is an unconditional edge — satisfied once the source step is done. An object ({"step": "triage", "when": {"is_true": "routine"}}) is a conditional edge: satisfied only while the source is done and the guard holds. Conditional edges out of one source into sibling steps are how a flow branches; pair them with Join::Any on the merge step. Unconditional edges serialize back to the plain string form, so existing documents round-trip unchanged.

Fields

step: String

The source step this edge depends on.

when: Option<Guard>

Optional condition; the edge is satisfied only while it holds.

Implementations

impl Edge

pub fn to(step: impl Into<String>) -> Self

An unconditional edge from step.

pub fn when(step: impl Into<String>, when: Guard) -> Self

A conditional edge from step, satisfied only while when holds.
