Detailed Description

template<typename T, size_t N>
class esphome::StaticRingBuffer< T, N >

Fixed-size circular buffer with FIFO semantics and iteration support.

A tiny ring buffer that avoids dynamic allocations from std::deque/std::queue (which can be wasteful on MCUs), while supporting iteration over queued elements.

Not thread-safe. All access (push/pop/iteration) must occur from a single context, or the caller must provide external synchronization.
