Samples

bacnet_ops::watch

Struct Samples 

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

A lease’s samples since it asked (Lease::samples). It holds at least WatchOptions::samples; a reader that falls behind loses the oldest, counted in dropped.

Implementations§

Source§

impl Samples

Source

pub fn try_next(&mut self) -> Option<Sample>

The next sample waiting, if one is.

Source

pub async fn next(&mut self) -> Option<Sample>

Wait for the next sample; None once the point is no longer watched and every sample was read. Cancel safe.

Source

pub fn dropped(&self) -> u64

Samples lost because this reader fell behind.
