pub struct Var(pub usize);

A handle to a node recorded on a Tape: its index into the tape.

Returned by every tape operation and passed back in to build further operations or to read a value or gradient.

Tuple Fields

0: usize

Trait Implementations

impl Clone for Var

fn clone(&self) -> Var

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Var

impl Debug for Var

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Var

impl Hash for Var

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Var

fn eq(&self, other: &Var) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
