Struct LayerSet

pub struct LayerSet { /* private fields */ }

The layers of one model and, optionally, the files they import.

Implementations

impl LayerSet

pub fn new() -> Self

An empty set that does not resolve imports.

pub fn push_layer(&mut self, bytes: Vec<u8>)

Adds a layer’s UTF-8 JSON bytes on top of the layers already added.

pub fn resolve_imports(&mut self)

Resolves imports, even if no import file is added: every import of every layer must then be one of the added files.

pub fn add_import(&mut self, uri: String, bytes: Vec<u8>)

Serves bytes for imports whose uri is exactly uri, and turns on import resolution.

pub fn len(&self) -> usize

Number of layers added.

pub fn is_empty(&self) -> bool

Whether no layer was added.

pub fn federate(&self) -> Result<IfcxFile, BindingError>

All layers merged into one file. Without imports, the layers’ schemas and data are concatenated in order. With imports, the layers are the imports of a synthetic main layer, each after the layers it imports, so a layer overrides its imports and the next layer overrides both. The header is that of the last layer in this order, the strongest.

pub fn compose(&self) -> Result<Composition, BindingError>

Flattens and composes the federated layers.

pub fn compose_json(&self) -> Result<String, BindingError>

The composed tree as JSON text: the artificial root over every root node, each node {"path", "attributes", "children"}.

pub fn to_glb(&self, settings: &GlbSettings) -> Result<Vec<u8>, BindingError>

The composed layers as a binary glTF 2.0 (.glb) file: their flat render scene with transformed, instanced meshes, lines and points and their materials, one glTF node per instance named by its IFCX path.

Geometry values that do not decode are left out of the scene, as RenderScene does; the file is still written.

pub fn validate_json(&self) -> Result<String, BindingError>

Checks the attributes of the federated layers against their merged schemas, those of resolved imports included (as openbim_ifcx::layers::LayerStack::validate does), and returns the report as JSON text: {"valid": bool, "failures": [{"node", "attribute", "pointer", "kind", "message"}]}. kind is a stable code such as missing-schema or type-mismatch.

Trait Implementations

impl Clone for LayerSet

fn clone(&self) -> LayerSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LayerSet

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

Formats the value using the given formatter.

impl Default for LayerSet

fn default() -> LayerSet

Returns the “default value” for a type.
