Struct FxChain 

pub struct FxChain { /* private fields */ }

Available on crate feature audio only.

An ordered chain of AudioProcessor stages applied in series.

The output of stage N becomes the input to stage N+1. An empty chain returns the input frame unchanged.

Example

let chain = FxChain::new()
    .push(normalizer)
    .push(resampler);
let output = chain.process(&input).await?;

Implementations

impl FxChain

pub fn new() -> FxChain

Create an empty FxChain.

pub fn push(self, processor: impl AudioProcessor + 'static) -> FxChain

Append a processing stage to the chain.

pub fn len(&self) -> usize

Returns the number of stages in the chain.

pub fn is_empty(&self) -> bool

Returns true if the chain has no stages.

Trait Implementations

impl AudioProcessor for FxChain

fn process<'life0, 'life1, 'async_trait>( &'life0 self, frame: &'life1 AudioFrame, ) -> Pin<Box<dyn Future<Output = Result<AudioFrame, AudioError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, FxChain: 'async_trait,

Process a single audio frame, returning the transformed result.

impl Default for FxChain

fn default() -> FxChain

Returns the “default value” for a type.
