Struct Graph 

pub struct Graph { /* private fields */ }

An index of supported records keyed by (node type, XMT identifier).

Implementations

impl Graph

pub fn parse(stream: &[u8]) -> Self

Parse supported fixed-record nodes from a neutral-binary stream.

pub fn get(&self, kind: u8, xmt: u32) -> Option<&Node>

Look up a node by record type and XMT identifier.

pub fn at_pos(&self, pos: usize) -> Option<&Node>

Look up the node whose type tag starts at pos.

pub fn of_kind(&self, kind: u8) -> impl Iterator<Item = &Node>

Iterate nodes of one record type in physical record order.

pub fn referenced_curve_xmts(&self) -> BTreeSet<u32>

Curve identities occupying typed curve-reference slots in the fixed topology and procedural graph.

pub fn unique_curve_edge_endpoints(&self, curve_xmt: u32) -> Option<[Point3; 2]>

Resolve the two model-space endpoints of the unique edge carrying a curve.

pub fn referenced_carrier_xmts(&self) -> BTreeSet<u32>

Carrier identities required by the surviving fixed topology image.

pub fn body_shape_shells(&self) -> Vec<&Node>

Return SHELL nodes whose ownership fields define a body shape.

pub fn has_complete_body_topology(&self) -> bool

Return whether every body-shape face has a non-empty valid loop chain and every non-null radial FIN partner belongs to the same reachable body topology.

pub fn body_shape_face_count(&self) -> usize

Count faces owned by validated body-shape shells.

pub fn face_loop_rings(&self, face_xmt: u32) -> Option<Vec<(u32, Vec<u32>)>>

Return the validated loop-to-FIN rings owned by a face.

The face’s loop chain must terminate at the null reference. Each loop points back to the face. Each FIN cycle closes at its first FIN, stays in the loop, and has reciprocal forward/backward links. Every FIN resolves its edge and vertex.

Trait Implementations

impl Debug for Graph

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

Formats the value using the given formatter.

impl Default for Graph

fn default() -> Graph

Returns the “default value” for a type.
