Enumeration Type Documentation

◆ ShrinkBehavior

enum gul14::ShrinkBehavior

Determine how a SlidingBuffer handles decreases of its size.

When the buffer's capacity decreases below the actual size some elements have to be dropped. The user can choose between two strategies:

  1. Keep the elements with the lower indices (ShrinkBehavior::keep_front_elements)
  2. Keep the elements with the higher indices (ShrinkBehavior::keep_back_elements)

Usually the more recent data shall be preserved, while older data can be dropped.

The behavior is utilized by SlidingBuffer::resize(), SlidingBuffer::reserve(), SlidingBufferExposed::resize(), and SlidingBufferExposed::reserve().
