rapidqueue

high performance c++ producer/consumer queues and executor utilities.

what it does

• provides lock-free queue variants for single and multi producer/consumer use cases
• provides blocking queue wrappers and runtime processors for async task handling
• includes executor utilities for scheduling, retries, throttling, key-based sharding, guarding, batching, and observability
• includes tests, benchmarks, and runnable examples

core behavior

• low contention fast path for producers and consumers
• fixed-capacity ring queues with explicit full/empty signaling
• typed interfaces for queue entries and task results
• practical runtime helpers for backoff, result receiving, and worker control
