Struct Variable 

pub struct Variable<T> {
    pub tensor: T,
    pub requires_grad: bool,
    pub id: usize,
}

A variable in the eager execution graph.

Wraps a tensor and tracks whether gradients should be computed for it.

Fields

tensor: T

The tensor data

requires_grad: bool

Whether this variable requires gradient computation

id: usize

Unique ID for gradient tracking

Implementations

impl<T> Variable<T>

pub fn new(tensor: T, requires_grad: bool) -> Self

pub fn constant(tensor: T) -> Self

Create a constant (no gradient).

pub fn tensor(&self) -> &T

Get a reference to the tensor.

pub fn requires_grad(&self) -> bool

Check if this variable requires gradients.
