Detailed Description

Ring buffer implementation.

This file provides a fixed-size circular buffer implementation that offers efficient FIFO operations. The ring buffer supports both fixed-size and dynamic-size configurations, and provides thread-safe operations.

Function Documentation

◆ operator==()

template<typename T, size_t N, bool C, bool Overwrite>

bool qb::detail::operator==	(	ring_buffer_iterator< T, N, C, Overwrite > const &	l,
		ring_buffer_iterator< T, N, C, Overwrite > const &	r )

noexcept

Equality comparison operator for ring buffer iterators.

Template Parameters

T	Element type
N	Buffer capacity
C	Whether the iterators are const
Overwrite	Whether the buffer overwrites old elements when full

Parameters

l	Left iterator
r	Right iterator

Returns: Whether the iterators are equal (based on count)

◆ operator!=()
