Trait VideoBackend 

pub trait VideoBackend: Send {
    // Required methods
    fn info(&self) -> BackendInfo;
    fn start(&mut self) -> Result<()>;
    fn stop(&mut self) -> Result<()>;
    fn next_event(&mut self, timeout: Option<Duration>) -> Result<CaptureEvent>;
}

A platform video capture implementation.

Contract: next_event returns PinrayError::Timeout when no event arrives within timeout (None = block forever), and must treat Some(Duration::ZERO) as a non-blocking poll. start/stop must be safe to call repeatedly and in either state.

Required Methods

fn info(&self) -> BackendInfo

fn start(&mut self) -> Result<()>

fn stop(&mut self) -> Result<()>

fn next_event(&mut self, timeout: Option<Duration>) -> Result<CaptureEvent>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
