Struct EvalHandle 

pub struct EvalHandle { /* private fields */ }

Lazy evaluation handle returned by eval().

Computes output shape from input shapes but defers actual evaluation until the caller chooses a consumption mode.

Implementations

impl EvalHandle

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

Output shape. Empty for scalar output, [n] for 1-D, [n, m] for 2-D, etc.

pub fn len(&self) -> usize

Total number of output elements.

pub fn is_empty(&self) -> bool

Whether the output is empty (zero elements due to empty input array).

pub fn scalar(self) -> Result<NumericResult, EvalError>

Consume as scalar. Errors if output is not 0-d.

pub fn to_array(self) -> Result<ArrayD<NumericResult>, EvalError>

Consume eagerly into a full N-dimensional array.

pub fn iter(self) -> EvalIter

Consume lazily — yields results as they become computable.

Trait Implementations

impl Debug for EvalHandle

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

Formats the value using the given formatter.
