pub struct OutputEvents<'a> { /* private fields */ }

Implementations§

Source §

impl<'a> OutputEvents<'a>

Source

pub unsafe fn try_push_unchecked( &mut self, event: impl Event, ) -> Result<(), Error>

§Safety

Events must be pushed in sample time order, i.e. event.header().time() must not be smaller than the time of the previous event successfully pushed.

Source

pub fn try_push(&mut self, event: impl Event) -> Result<(), Error>
