Trait Implementations

impl AudioNode for AudioParam

fn registration(&self) -> &AudioContextRegistration

fn channel_config_raw(&self) -> &ChannelConfig

fn channel_config_cloned(&self) -> ChannelConfig

fn number_of_inputs(&self) -> u32

The number of inputs feeding into the AudioNode. For source nodes, this will be 0.

fn number_of_outputs(&self) -> u32

The number of outputs coming out of the AudioNode.

fn channel_count_mode(&self) -> ChannelCountMode

Represents an enumerated value describing the way channels must be matched between the node’s inputs and outputs.

fn channel_interpretation(&self) -> ChannelInterpretation

Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen.

fn channel_count(&self) -> usize

Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.

fn id(&self) -> &AudioNodeId

fn context(&self) -> &BaseAudioContext

The BaseAudioContext which owns this AudioNode.

fn connect<'a>(&self, dest: &'a dyn AudioNode) -> &'a dyn AudioNode

Connect the output of this AudioNode to the input of another node.

fn connect_at<'a>(
    &self,
    dest: &'a dyn AudioNode,
    output: u32,
    input: u32
) -> Result<&'a dyn AudioNode, IndexSizeError>

Connect a specific output of this AudioNode to a specific input of another node.

fn disconnect<'a>(&self, dest: &'a dyn AudioNode) -> &'a dyn AudioNode

Disconnects all outputs of the AudioNode that go to a specific destination AudioNode.

fn disconnect_all(&self)

Disconnects all outgoing connections from the AudioNode.

fn set_channel_count_mode(&self, v: ChannelCountMode)

fn set_channel_interpretation(&self, v: ChannelInterpretation)

fn set_channel_count(&self, v: usize)
