Tensor 基础 trait：所有张量必须实现的核心操作

提供形状、数据类型、设备等基本信息查询

Required Methods

fn shape(&self) -> &[usize]

获取张量的形状（各维度大小）

fn dtype(&self) -> DType

获取数据类型

fn device(&self) -> Device

获取设备类型

fn to_dense(&self) -> DenseTensor

转换为密集张量

fn to_sparse(&self) -> Option<SparseTensor>

转换为稀疏张量（如果适用）

Provided Methods

fn ndim(&self) -> usize

获取张量的维度数（rank）

fn numel(&self) -> usize

获取总元素数量

fn is_scalar(&self) -> bool

检查是否为标量（0 维张量）

fn is_vector(&self) -> bool

检查是否为向量（1 维张量）

fn is_matrix(&self) -> bool

检查是否为矩阵（2 维张量）

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
