ChunkProducer

Struct ChunkProducer 

Source
pub struct ChunkProducer { /* private fields */ }
Expand description

加工スレッド側のハンドル。DROP_OLDEST 方針で push する。

Implementations§

Source§

impl ChunkProducer

Source

pub fn push(&mut self, chunk: AudioChunk) -> Option<u64>

チャンクを push する。満杯なら最古を捨て(DROP_OLDEST)、捨てた数を数える。

dropped_before には、このチャンクが入るまでに累計で捨てたチャンク数 (このチャンクのための追い出し 1 件を含む)を入れる。消費側は連続チャンクの dropped_before の差分で直前の欠落数を、絶対値で累計欠落数を知れる。

この push でドロップが起きたら Some(累計ドロップ数) を返す (crate::types::Event::ChunkDropped の発火判断に使える)。起きなければ None

Source

pub fn dropped_count(&self) -> u64

これまでに DROP_OLDEST で捨てた累計チャンク数。
