My understanding from reading other blogs on TigerBeetle (and the Power of Ten rule) is that it's not that they aren't allocating at all. It's all static allocation up front. Zig makes these far easier to manage with its use of Allocators. Rust wants everything to be RAII, tons of little allocations who's lifetimes are managed by the borrow checker. You can use other patterns in Rust of course but you're fighting the borrow checker.

Zig gives you a lot of tools to enforce correctness in simple and straightforward ways, where as Rust comes with a lot of complexity. TigerBeetle isn't the first project to talk about this, Richard Feldman also points out similar advantages to Zig over Rust as the reasoning for the Roc compilers rewrite from Rust to Zig.
