Struct RingBufferReader 

pub struct RingBufferReader<T, const N: usize> { /* private fields */ }

Implementations

impl<T, const N: usize> RingBufferReader<T, N>

pub fn pull(&mut self) -> Option<T>

Pull an element from the RingBuffer. It returns None if the RingBuffer is empty.

        println!("{} elem/s", COUNTER.swap(0, Ordering::Relaxed));
    }
}

pub fn is_empty(&mut self) -> bool

Check if the RingBuffer is empty and evenutally updates the internal cached indexes.
