Struct GeometryGraphBuilder

pub struct GeometryGraphBuilder { /* private fields */ }

Append-only builder that makes cycles and dangling references unrepresentable.

Implementations

impl GeometryGraphBuilder

pub const fn new() -> Self

Create an empty builder.

pub fn push(&mut self, node: GeometryNode) -> Result<NodeId, GraphError>

Insert a node. Every reference must be to an earlier node.

pub fn push_value<T>(&mut self, value: T) -> Result<NodeId, GraphError>

where T: BuiltInNode,

Insert one canonical representation without spelling its enum variant.

The accepted set is deliberately sealed; adapters must translate custom values into a built-in neutral representation before graph construction.

pub fn finish(self, roots: Vec<NodeId>) -> Result<GeometryGraph, GraphError>

Freeze the graph after validating roots.

Trait Implementations

impl Debug for GeometryGraphBuilder

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

Formats the value using the given formatter.

impl Default for GeometryGraphBuilder

fn default() -> Self

Returns the “default value” for a type.
