Nim Memory Management Architecture: ARC, ORCP, and Concurrency Tradeoffs
A practical guide to choosing between ARC and ORCP in Nim, covering memory boundaries, atomic overhead, and failure modes for high-performance systems.
Nim's ARC/ORC: Deterministic Memory Management Without the GC Pauses
Nim 2.0's ARC/ORC memory management gives you deterministic deallocation without GC pauses. This blog covers ownership semantics, cycle collection, migration friction, and a worked cyclic-list example—plus the trade-offs you'll hit in production.
Diagnosing Memory Leaks and Cycle Bloat in Nim ARC/ORC
Learn how to diagnose and fix memory leaks and reference cycles in Nim using ARC and ORC. This guide covers --debug:memleak, ownership annotations, and breaking cycles with {.weak.}.
Nim's ORC Mode: Making CLI Tools Feel Native with Deterministic Cleanup
Nim's ORC memory management mode provides deterministic destruction for latency-sensitive CLI tools by using reference counting instead of tracing GC, but requires careful ownership design to avoid leaks.
Nim's ORC: Deterministic Memory Management Without a Garbage Collector
Nim's Optimized Reference Counting (ORC) delivers deterministic destruction without a garbage collector, making it suitable for embedded, real‑time, and WASM targets. This post walks through how ORC works, a cyclic data‑structure example, and the trade‑offs you must accept.
Nim’s Deterministic Memory Management: Choosing ARC/ORC Over the Traditional Garbage Collector
Nim offers deterministic ARC/ORC memory modes that eliminate unpredictable GC pauses, making them ideal for real‑time and embedded workloads.
Architecture Note: Using Nimble’s Lockfile for Reproducible Dependency Resolution
Commit both .nimble manifests and nimble.lock files to guarantee deterministic builds across machines and CI pipelines.
Nim Macros: Compile-Time Getter/Setter Generation to Cut Boilerplate
Nim macros generate getter and setter methods at compile time, eliminating repetitive boilerplate without runtime overhead.
