RecordingHandle

Struct RecordingHandle 

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

录制句柄(用于控制和监控)

§Drop 语义

RecordingHandle 被丢弃时:

  • ✅ 自动 flush 缓冲区中的数据
  • ✅ 自动关闭接收端
  • ❌ 不会自动保存文件(需要显式调用 stop_recording()

§Panics

如果在 Drop 时发生 I/O 错误,错误会被静默忽略(Drop 上下文无法处理错误)。 建议始终显式调用 stop_recording() 以获取错误结果。

Implementations§

Source§

impl RecordingHandle

Source

pub fn frame_count(&self) -> u64

获取当前已录制的帧数(线程安全,无阻塞)

§返回

当前已成功录制的帧数

Source

pub fn dropped_count(&self) -> u64

获取当前丢帧数量

Source

pub fn is_stop_requested(&self) -> bool

检查是否已请求停止(用于循环条件判断)

Source

pub fn stop(&self)

手动停止录制(请求停止)

Source

pub fn elapsed(&self) -> Duration

获取录制时长

Source

pub fn output_path(&self) -> &PathBuf

获取输出文件路径

Trait Implementations§

impl Drop for RecordingHandle

Source§

fn drop(&mut self)

⚠️ Drop 语义:自动清理资源

注意:这里只关闭接收端,不保存文件。 文件保存必须在 stop_recording() 中显式完成。
