Struct DecodedAudioSources 

pub struct DecodedAudioSources { /* private fields */ }

Decoded, project-rate planar audio held per source audio stream for offline mixing; one whole-stream block each, indexed by absolute source position.

Implementations

impl DecodedAudioSources

pub fn new() -> Self

Creates an empty cache.

pub fn insert(&mut self, source: SourceId, block: AudioBlock)

Retains one source’s decoded default audio stream, replacing any earlier block.

pub fn insert_stream( &mut self, source: SourceId, stream: Option<u32>, block: AudioBlock, )

Retains audio stream stream of a source (AudioProperties::stream), replacing any earlier block.

pub fn remove(&mut self, source: &SourceId) -> bool

Drops every stream of one source’s decoded audio.

pub fn len(&self) -> usize

Returns how many source streams are retained.

pub fn is_empty(&self) -> bool

Returns whether no source is retained.

Trait Implementations

impl AudioBlockProvider for DecodedAudioSources

Each block is its source’s entire audio; outside it the source is silent.

fn block( &self, source: &SourceId, stream: Option<u32>, _start_sample: i64, _frames: usize, ) -> Option<AudioSpan<'_>>

Returns source samples [start_sample, start_sample + frames) at the project rate, as a span that covers all of them.

impl Default for DecodedAudioSources

fn default() -> Self

Returns the “default value” for a type.
