Enum Missing 

pub enum Missing {
    Default,
    Input(ReadPlan),
    Scalar(usize),
    Invalid,
}

What an unmapped position reads. Input plans use the output position and are invalid beyond their end. Scalar broadcasts one source item.

Variants

Default

Input(ReadPlan)

Scalar(usize)

Invalid

Implementations

impl Missing

pub fn prototype(dtype: DType, sources: &mut Vec<Binding<'_>>) -> Self

The read of a missing position in a copy of dtype items from sources. A character copy reads its prototype, a space, from one more source it adds, so projecting the sources to codes keeps the space. Other dtypes read their default.
