Struct MultiInputNode 

pub struct MultiInputNode { /* private fields */ }

A node with a configurable number of inputs and outputs.

Used for fan-in topologies where multiple upstream outputs are combined.

Implementations

impl MultiInputNode

pub fn new(inputs: u32, outputs: u32, name: impl Into<String>) -> Self

Create a new multi-input node.

All ports are typed as Any (video or audio).

pub fn with_id(self, id: NodeId) -> Self

Set the node ID.

pub fn input_count(&self) -> usize

Return the number of input ports.

pub fn output_count(&self) -> usize

Return the number of output ports.
