Struct PartitionError 

pub struct PartitionError {
    pub flat_graph: Box<DfirGraph>,
    pub diagnostic: Diagnostic,
}

The error returned by partition_graph when partitioning fails.

This hands back the original flat graph alongside the diagnostic, so callers can visualize the graph to diagnose the cycle that prevented partitioning.

Fields

flat_graph: Box<DfirGraph>

The pristine, un-partitioned flat graph (returned so it can still be rendered).

Boxed because a DfirGraph is large (hundreds of bytes) and this keeps the Err variant of partition_graph’s result small; the allocation only happens on the (cold) failure path.

diagnostic: Diagnostic

The diagnostic explaining why partitioning failed (names the offending cycle).
