Learn how to select Nim's ARC/ORC memory management for deterministic, low‑latency services, with concrete build commands, FFI safety rules, and verification steps.
Nim's concepts let you declare compile-time requirements on generic parameters, moving type errors from deep inside generic code to the call site. This guide defines a Comparable concept, applies it to a generic findMin, and covers scope pitfalls, version requirements, and verification.
Learn how Nim's compile-time macros eliminate boilerplate and runtime reflection by manipulating the AST, allowing for high-performance code generation without runtime overhead.
Learn how to select Nim's ARC or ORC memory model for deterministic, low‑latency systems, understand trust/data boundaries, and break reference cycles with WeakRef to avoid leaks.
Learn how Nim's ARC and ORC provide deterministic destruction, eliminate GC pauses, and improve C/C++ interoperability, with configuration tips and pitfalls.
Learn how to call C's printf from Nim using the FFI pragma, compile with the correct linker flags, verify the output, and troubleshoot common linking issues.
Stop-the-world GC pauses can ruin real-time performance. Learn how Nim's ARC and ORC provide deterministic memory management and how to handle reference cycles.
Mixing meters and seconds compiles in most languages. Nim's distinct types catch that at compile time with no runtime overhead, forcing explicit conversions for semantically different values that share a representation.
Compile Nim with --gc:orc to get reference counting plus an incremental cycle collector, giving deterministic cleanup and low latency for graph‑heavy services while avoiding stop‑the‑world pauses.
