Struct RingBufferWriter 

pub struct RingBufferWriter<T> { /* private fields */ }

Writer handle of the ringbuffer.

Implementations

impl<T> RingBufferWriter<T>

pub fn capacity(&self) -> usize

Returns the capacity (number of slots) of the ringbuffer.

pub fn push(&mut self, t: T) -> Option<T>

Push an element into the RingBuffer.

Returns Some(T) when the buffer is full (giving back ownership of the value), otherwise returns None on success.

pub fn is_full(&mut self) -> bool

Check if the RingBuffer is full.
