Expand description

A read position in a queue.

Implementations§

Source§

impl ReadPosition

Source

pub fn is_past(&self, write: &WritePosition) -> Option<bool>

A WritePosition can be compared to a ReadPosition correctly if the ring buffer wrapped around at most 2³¹ (2 to the power of 31) times.

Returns None if the read position and the write position cannot be compared, Some(true) if the read position is strictly higher than the write position, Some(false) otherwise
