RealtimeCommand

Struct RealtimeCommand 

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

实时命令类型(统一使用 FrameBuffer)

设计决策:不再区分 Single 和 Package,统一使用 FrameBuffer。

  • Single 只是 len=1 的 FrameBuffer
  • 简化 TX 线程逻辑(不需要 match 分支)
  • 消除 CPU 分支预测压力

Implementations§

Source§

impl RealtimeCommand

Source

pub fn single(frame: PiperFrame) -> Self

创建单个帧命令(向后兼容)

性能优化:添加 #[inline] 属性,因为此方法处于热路径(Hot Path)上。

Source

pub fn package(frames: impl IntoIterator<Item = PiperFrame>) -> Self

创建帧包命令

性能优化:添加 #[inline] 属性,因为此方法处于热路径(Hot Path)上。

注意:如果用户传入 Vec<PiperFrame>into_iter() 会消耗这个 Vec。 如果 Vec 长度 > 6,SmallVec 可能会尝试重用 Vec 的堆内存或重新分配。 虽然这是安全的,但为了最佳性能,建议用户传入数组(栈分配)。

Source

pub fn len(&self) -> usize

获取帧数量

Source

pub fn is_empty(&self) -> bool

检查是否为空

Source

pub fn iter(&self) -> impl Iterator<Item = &PiperFrame>

获取帧迭代器(用于 TX 线程发送)

Source

pub fn into_frames(self) -> FrameBuffer

消费并获取帧(用于 TX 线程发送)
