EffectSink

Struct EffectSink 

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

Effect 输出缓冲(写入端)。

由 ExecutionShell 持有,跨 step() 调用复用(clear 而非 drop+new), 实现热路径零分配(轴①)。

模块通过 &mut EffectSink 参数写入 effect,driver 通过 as_slice() 读取。 原草稿中 EffectBuffer / EffectBatch<'_> / EffectSink 三个名字统一为此类型 (审查意见2 S4 落实)。
