Struct DenseWeights 

Source 
pub struct DenseWeights<'view, A, T, Id, I, P>
where
    A: PropertyAxis,
    I: PropertyIndex,
    P: ArrowPrimitiveType,
{ /* private fields */ }
Expand description

Selected dense primitive weights bound to one axis of a topology view.

A is one of ElementAxis, RelationAxis, or IncidenceAxis; the per-axis new constructor selects the right topology bound.

§Performance

Weight lookup is O(1).

Implementations§

Source§

impl<'view, A, T, Id, I, P> DenseWeights<'view, A, T, Id, I, P>
where A: PropertyAxis, T: AxisIndex<A>, I: PropertyIndex, P: ArrowPrimitiveType,

Source

pub fn new( topology: &'view T, layer: &'view PropertyLayer<Id, I>, ) -> Result<Self, PropertyError>

Selects a dense primitive layer as weights for topology along axis A (ElementAxis, RelationAxis, or IncidenceAxis).

§Errors

Returns PropertyError if the layer is not A-keyed, dense, primitive type P, non-null, or long enough.

§Performance

Validation is O(layer.len()) for the null check.
