Struct VoidIndex 

pub struct VoidIndex { /* private fields */ }

Index mapping host elements to their voids

Provides efficient lookup of void entity IDs for any host element, enabling void-aware geometry processing.

Implementations

impl VoidIndex

pub fn new() -> Self

Create an empty void index

pub fn from_content<T>(content: &T, decoder: &mut EntityDecoder<'_>) -> Self

where T: AsRef<[u8]> + ?Sized,

Build void index from IFC content

Scans the content for IfcRelVoidsElement entities and builds the host-to-void mapping.

Arguments

• content - The raw IFC file content
• decoder - Entity decoder for parsing

Returns

A populated VoidIndex

pub fn add_relationship(&mut self, host_id: u32, void_id: u32)

Add a void relationship

pub fn get_voids(&self, host_id: u32) -> &[u32]

Get void IDs for a host element

Arguments

• host_id - The entity ID of the host element

Returns

Slice of void entity IDs, or empty slice if no voids

pub fn get_host(&self, void_id: u32) -> Option<u32>

Get the host ID for a void element

Arguments

• void_id - The entity ID of the void/opening

Returns

The host entity ID, if found

pub fn has_voids(&self, host_id: u32) -> bool

Check if an element has any voids

pub fn void_count(&self, host_id: u32) -> usize

Get number of voids for a host element

pub fn host_count(&self) -> usize

Get total number of host elements with voids

pub fn total_relationships(&self) -> usize

Get total number of void relationships

pub fn iter(&self) -> impl Iterator<Item = (u32, &[u32])>

Iterate over all host elements and their voids

pub fn hosts_with_voids(&self) -> Vec<u32>

Get all host IDs that have voids

pub fn is_void(&self, entity_id: u32) -> bool

Check if an entity is a void/opening

pub fn is_host_with_voids(&self, entity_id: u32) -> bool

Check if an entity is a host with voids

Trait Implementations

impl Clone for VoidIndex

fn clone(&self) -> VoidIndex

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VoidIndex

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

Formats the value using the given formatter.

impl Default for VoidIndex

fn default() -> Self

Returns the “default value” for a type.
