Struct AudioGraph 

pub struct AudioGraph {
    pub nodes: HashMap<String, AudioNode>,
    pub routes: Vec<AudioRoute>,
    pub master: String,
}

Audio Graph: collection of nodes and routes

Fields

nodes: HashMap<String, AudioNode>

All nodes by ID

routes: Vec<AudioRoute>

All routes (connections)

master: String

Master output node ID (always present)

Implementations

impl AudioGraph

pub fn new() -> Self

Create new empty graph with master output

pub fn add_node(&mut self, node: AudioNode) -> Result<()>

Add node to graph

pub fn add_route(&mut self, route: AudioRoute) -> Result<()>

Add route to graph (validates source and destination exist)

pub fn upsert_bus( &mut self, id: impl Into<String>, alias: Option<String>, effects: Option<Value>, ) -> Result<()>

Add or update a bus node. This is used for routing declarations, where repeated declarations may add effects to an existing bus.

pub fn from_routing_setup(routing_setup: &RoutingSetup) -> Self

Build the canonical graph from the interpreter routing setup.

pub fn get_node(&self, id: &str) -> Option<&AudioNode>

Get node by ID

pub fn get_node_mut(&mut self, id: &str) -> Option<&mut AudioNode>

Get mutable node by ID

pub fn get_routes_from(&self, node_id: &str) -> Vec<&AudioRoute>

Get all routes from a node

pub fn get_routes_to(&self, node_id: &str) -> Vec<&AudioRoute>

Get all routes to a node

pub fn node_count(&self) -> usize

Count total nodes

pub fn route_count(&self) -> usize

Count total routes

pub fn validate(&self) -> Result<()>

Validate graph consistency

pub fn node_names(&self) -> Vec<String>

Get all node names.

pub fn has_node(&self, node_id: &str) -> bool

Check if a node exists.

pub fn optimized(&self) -> Self

Return an optimized copy with duplicate mix routes merged and node effects normalized.

Trait Implementations

impl Clone for AudioGraph

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioGraph

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

Formats the value using the given formatter.

impl Default for AudioGraph

fn default() -> Self

Returns the “default value” for a type.
