sqlightning VS wabt

I'm guessing you mean "and the software is fast enough", because OpenLDAP itself has been the world's fastest distributed database for over a decade, and nothing else even comes close.

Since you built on top of SQLite, then you're already at least an order of magnitude slower. You could speed it up a bit by using SQLightning, which replaces SQLite's Btree engine with OpenLDAP's.

This has been shared without context but I guess the SQLite team is starting to modularize the btree code in order to facilitate work like SQLightning: https://github.com/LMDB/sqlightning

At the time SQLightning greatly improved SQLite performance but due to LMDB's requirement to have keys fit in 2/3 of a page it wasn't really useful as a general purpose replacement of SQLite's internal b-tree implementation.

https://github.com/WebAssembly/wabt/blob/main/wasm2c/README.... is a straightforward way to take an untrusted application (compiled already to wasm) and turn it into C that you can embed into your application or compile to a linkable DLL. I believe this approach has been used to sandbox untrusted libraries in production by Mozilla: https://hacks.mozilla.org/2021/12/webassembly-and-back-again...

As long as this is happening, might as well try some of my favorites: https://github.com/wasm3/wasm3, https://github.com/WebAssembly/wabt, https://github.com/bytecodealliance/wasmtime

This seems sort of like understanding machine code vs assembly; it's much easier to learn WAT and translate to/from WASM as necessary using the wabt tools [0].

Either way its super cool how simple WebAssembly is, you can really get your hands dirty and understand exactly every detail of how your program runs!

You mean this? https://github.com/WebAssembly/wabt/blob/main/wasm2c/README....

That seems like quite an undertaking. But at that point, It would make sense to cut out WASM entirely like https://datastation.multiprocess.io/blog/2022-05-12-sqlite-i...

The .wat file can be compiled to a .wasm using wat2wasm which is part of the WebAssembly Toolkit CLI tools:

it is in C++ https://github.com/WebAssembly/wabt/blob/main/src/tools/wat2wasm.cc

I don't think you are building an application that will use Native Client technologies How to extract source code from Native Client .nexe file, migrate to WebAssembly? #1864 so that would be superfluous, and frankly, useless in your case.

I'm trying to get a basic Rust webassembly program, then porting it to C via wasm2c. The example works, but when I use wasm-bindgen and analyze it with wasm2wat, I get an import "env". The issue is that in C (wasm2c) it comes out as struct Z_env_instance_t; and I can't instantiate it (as in Z_env_instance_t env; to pass it's address to Z_wasm_client_bg_instantiate.
