Module queues 

Real-time safe command queues for automation

Non-blocking queues for the dual-thread architecture

This module provides queues for safe data exchange between the control thread (soft RT) and the signal processing thread (hard RT).

Components

• SpscQueue — Single-producer single-consumer queue (maximum throughput)
• RtQueueBase — Base trait for all queues
• QueueError — Queue operation error type
• OverflowPolicy — Overflow behaviour policies
• UnderflowPolicy — Underflow behaviour policies

ring

Lock-free ring buffer for real-time use.

rt_queue

Base real-time queue implementation.

signal

Signal and command types for queues.

spsc

Lock-free single-producer single-consumer queue.

telemetry

Telemetry data types (future functionality). Telemetry types — event data from the signal processing world.

telemetry_block

Telemetry block batching utilities.

Structs

QueueStats

Live queue statistics collected inside the queue.

QueueStatsSnapshot

Point-in-time snapshot of queue statistics.

Enums

OverflowPolicy

Overflow behaviour policy for bounded queues.

Underflow behaviour policy for bounded queues.

Traits

RtQueueBase

Base trait for all real-time safe queues.

Functions
