Struct FeatureRef 

#[non_exhaustive]
pub struct FeatureRef {
    pub layer: LayerId,
    pub fid: i64,
    pub part: Option<u32>,
}

Feature provenance within a topology, including an optional original part index.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

layer: LayerId

Topology-scoped layer ID.

fid: i64

Signed feature ID, unique within its layer.

part: Option<u32>

Zero-based depth-first part index, including skipped degenerate parts. None means multiple parts contributed or no single part is identified.
