mesh-sieve 4.0.1

//! Top-level module for mesh topology abstractions.
//!
//! This module provides the core types and traits for representing mesh topologies using the Sieve abstraction.
//! It includes:
//! - Arrow and point types for mesh connectivity
//! - The Sieve trait and in-memory implementation
//! - Stack and stratum utilities for advanced mesh operations
//!
//! Most users will interact with the `Sieve` trait and the `InMemorySieve` implementation for building and traversing mesh topologies.

//! ## Edge uniqueness
//! A topology stores a *set* of arrows: for any `(src, dst)` pair there is at most one edge.
//! Insertion behaves as an upsert, replacing existing payloads (and orientations) in place.
//! Duplicate edges are forbidden; debug builds assert that the outgoing and incoming maps
//! remain perfect mirrors and contain no parallel edges.
