Enum ValueOrView 

pub enum ValueOrView<'a> {
    View(ValueView<'a>),
    Value(Value),
}

Value type used for model inputs that can be either owned or borrowed.

These can be created from a shape and data (see ValueView::from_shape and Value::from_shape) or from a tensor of a supported type (Tensor, TensorView etc.) using Into.

Variants

View(ValueView<'a>)

A borrowed view (like a slice).

These are created from slices or tensor views of a supported element type.

Value(Value)

An owned value (like a Vec<T>).

These are created from Vec<T>s or owned tensors of a supported element type.
