Struct GeometryGraph 

pub struct GeometryGraph { /* private fields */ }

Immutable acyclic geometry graph with one or more roots.

Implementations

impl GeometryGraph

pub fn len(&self) -> usize

Number of nodes.

pub fn is_empty(&self) -> bool

Whether the graph has no nodes.

pub fn get(&self, id: NodeId) -> Option<&GeometryNode>

Read a node by typed handle. A handle owned by another graph returns None.

pub fn roots(&self) -> &[NodeId]

Output roots in caller-specified order.

pub fn iter(&self) -> impl ExactSizeIterator

All nodes in stable topological insertion order.

impl GeometryGraph

pub fn to_json(&self) -> Result<String, WireError>

This graph as a JSON payload of the wire format; see to_json.

Errors

WireError::NonFinite if the graph holds a NaN or an infinity.

pub fn from_json(text: &str) -> Result<GeometryGraph, WireError>

A graph read from a JSON payload of the wire format; see from_json.

Errors

A named WireError for every payload that cannot be read whole.

pub fn to_cbor(&self) -> Result<Vec<u8>, WireError>

This graph as a CBOR payload of the wire format; see to_cbor.

Errors

WireError::NonFinite if the graph holds a NaN or an infinity.

pub fn from_cbor(bytes: &[u8]) -> Result<GeometryGraph, WireError>

A graph read from a CBOR payload of the wire format; see from_cbor.

Errors

A named WireError for every payload that cannot be read whole.

Trait Implementations

impl Debug for GeometryGraph

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

Formats the value using the given formatter.

impl Default for GeometryGraph

fn default() -> GeometryGraph

Returns the “default value” for a type.

impl PartialEq for GeometryGraph

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

Equality operator ==.
