Struct MaterialLayerFlat 

pub struct MaterialLayerFlat {
    pub element_ids: Vec<u32>,
    pub axis: Vec<u32>,
    pub layer_counts: Vec<u32>,
    pub direction_sense: Vec<f64>,
    pub offset: Vec<f64>,
    pub layer_material_ids: Vec<u32>,
    pub layer_thicknesses: Vec<f64>,
}

Flat, wire-friendly encoding of a MaterialLayerIndex, produced by MaterialLayerIndex::to_flat and reconstructed by MaterialLayerIndex::from_flat.

The streaming pre-pass builds the index ONCE (from the IfcRelAssociatesMaterial spans it already collected) and ships this encoding to every geometry worker, so each worker’s first processGeometryBatch skips the per-worker MaterialLayerIndex::from_content full-file decode scan. All fields are SoA parallel arrays so they cross the wasm/JS boundary as plain typed arrays:

• element_ids[i] — the element express id of record i.
• axis[i] — 0 = NotSliceable; 1/2/3 = sliceable along Axis1/Axis2/Axis3.
• layer_counts[i] — number of layers of record i (0 for NotSliceable).
• direction_sense[i], offset[i] — the sliceable scalars (0.0 for NotSliceable).
• layer_material_ids / layer_thicknesses — per-layer values, concatenated in record order; record i consumes layer_counts[i] entries starting after the layers of every earlier record.

Trait Implementations

impl Clone for MaterialLayerFlat

fn clone(&self) -> MaterialLayerFlat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaterialLayerFlat

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

Formats the value using the given formatter.

impl Default for MaterialLayerFlat

fn default() -> MaterialLayerFlat

Returns the “default value” for a type.

impl PartialEq for MaterialLayerFlat

fn eq(&self, other: &MaterialLayerFlat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
