Struct PropertyLayer 

pub struct PropertyLayer<Id, I>
where
    I: PropertyIndex,
{ /* private fields */ }

Arrow-backed property layer.

Performance

Cloning is O(1) for Arrow buffers plus descriptor clone cost.

Implementations

impl<Id, I> PropertyLayer<Id, I>

where I: PropertyIndex,

pub fn try_new_dense( descriptor: PropertyLayerDescriptor<Id, I>, values: ArrayRef, ) -> Result<Self, PropertyError>

Builds a dense Arrow-backed property layer.

Errors

Returns PropertyError when storage, Arrow type, or nullability is invalid.

Performance

Validation is O(values.len()) only when nullability must be checked.

pub fn try_new_sparse( descriptor: PropertyLayerDescriptor<Id, I>, len: usize, indices: Arc<PrimitiveArray<I::ArrowType>>, values: ArrayRef, default: Option<ArrayRef>, ) -> Result<Self, PropertyError>

Builds a sparse Arrow-backed property layer.

Errors

Returns PropertyError when storage, Arrow type, default policy, sparse index ordering, or nullability is invalid.

Performance

Validation is O(indices.len() + default length).

pub const fn descriptor(&self) -> &PropertyLayerDescriptor<Id, I>

Returns this layer’s descriptor.

Performance

This function is O(1).

pub const fn data(&self) -> &PropertyLayerData<I>

Returns this layer’s data.

Performance

This function is O(1).

pub const fn len(&self) -> usize

Returns the logical layer length.

Performance

This function is O(1).

pub const fn is_empty(&self) -> bool

Returns whether the logical layer is empty.

Performance

This function is O(1).
