1//! Default concrete type implementations.
2//!
3//! This module provides the default concrete types for tensor network operations:
4//!
5//! - [`DynId`]: Runtime identity (UUID-based unique identifier)
6//! - [`TagSet`]: Tag set for metadata (Arc-wrapped for cheap cloning)
7//! - [`Index`]: Generic index type (`Index<Id, Tags>`)
8//! - [`DynIndex`]: Default index type (`Index<DynId, TagSet>`)
9//! - [`IdxTensor`]: Dense tensor with dynamic rank
10//!
11//! Linear algebra operations:
12//! - [`svd::svd`]: Singular Value Decomposition
13//! - [`qr::qr`]: QR decomposition
14//! - [`factorize::factorize`]: Unified factorization interface
15//! - [`direct_sum::direct_sum`]: Direct sum of tensors
16//!
17//! These types are suitable for most tensor network applications and provide
18//! a good balance of flexibility and performance.
