Hey folks, this is my project. I really liked OxCaml's zero_alloc feature [0], something you don't get in Rust or Zig or Go*, and have been trying to get a handle on allocations in The Consensus's code search engine.
It's an extremely early project but it's been helping me out a bunch already. Would love to hear your bug reports or requests if you try running it on your codebase.

* I think you can get this in Clang and maybe GCC with `__attribute__((nonallocating))` though.
Rust has a mode where no allocator is available.
No allocator available isn't the same as being able to enforce no allocations.
that option in rust allows to set own allocator, which may be disabled after initial allocation, may be per thread.
