Struct Graph 

pub struct Graph { /* private fields */ }

A multichannel graph is a set of root nodes, one per output channel.

Implementations

impl Graph

pub fn new() -> Self

Creates an empty graph.

pub fn render<R>(self, roots: R) -> Self

where R: Into<GraphRoots>,

Adds one or more output roots and returns the graph.

pub fn root<R>(self, roots: R) -> Self

where R: Into<GraphRoots>,

Backward-compatible alias for render.

pub fn with_root<R>(self, roots: R) -> Self

where R: Into<GraphRoots>,

Backward-compatible alias for render.

pub fn mount(&self) -> Result<MountedGraph, MountError>

Lowers the graph and keeps mounted-node handles for direct updates.

Returns Err(MountError::DuplicateKey(...)) if two nodes in the graph share the same key prop.

pub fn mount_with_id_counter( &self, next_id: &mut NodeId, ) -> Result<MountedGraph, MountError>

Lowers the graph using an external node-ID counter.

Each call advances next_id past all allocated IDs. This allows successive graph rebuilds to produce unique node IDs within the same runtime session, avoiding NodeAlreadyExists errors.

Returns Err(MountError::DuplicateKey(...)) if two nodes in the graph share the same key prop.

pub fn push_root(&mut self, node: Node)

Adds one root node.

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

Returns the graph roots.

pub fn lower(&self) -> InstructionBatch

Lowers the graph into a runtime instruction batch.

Panics if the graph contains duplicate keyed nodes. Prefer [mount] for fallible access.

Trait Implementations

impl Clone for Graph

fn clone(&self) -> Graph

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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.
