Struct LodIndex 

pub struct LodIndex { /* private fields */ }

Validated deterministic LOD hierarchy.

Implementations

impl LodIndex

pub fn try_new(nodes: impl IntoIterator<Item = LodNode>) -> LodResult<Self>

Validates nodes, reciprocal parent links, roots, reachability, and cycles.

pub fn node(&self, id: NodeId) -> Option<&LodNode>

Finds a node.

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

Root IDs in deterministic order.

pub fn nodes(&self) -> impl ExactSizeIterator<Item = &LodNode>

All nodes ordered by ID.

Trait Implementations

impl Clone for LodIndex

fn clone(&self) -> LodIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LodIndex

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

Formats the value using the given formatter.

impl PartialEq for LodIndex

fn eq(&self, other: &LodIndex) -> 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.
