Memory Arenas in Rust: Bump Allocators & Sub-Nanosecond Allocation Lifecycles

An advanced Rust systems performance guide to custom memory allocators. We dissect bump allocation mechanics (bumpalo), typed arena pools, cache locality optimization, and eliminating heap fragmentation in high-throughput loops.

Zig for Systems Engineers in 2026: Manual Memory Arenas, Comptime & Seamless C Interop

An in-depth systems programming guide to Zig 0.14. We examine explicit memory allocator passing, arena allocations, compile-time metaprogramming (comptime), drop-in C/C++ compilation, and building high-throughput low-level tools.
