Struct LoopId 

pub struct LoopId {
    pub min_vertex: VertexId,
    pub len: u32,
    pub hash: u64,
}

A content fingerprint of a boundary loop, valid across edits and transactions for as long as the loop’s vertex sequence is unchanged.

Fields

min_vertex: VertexId

The smallest vertex id on the loop.

len: u32

The number of vertices on the loop.

hash: u64

FNV-1a 64 over the little-endian bytes of the vertex ids in BoundaryLoop::vertices order: for a closed loop, starting at min_vertex; for an open chain, from its first end.
