Isn't wasm-tools for working with Wasm modules? Maybe I'm missing something. I was using Binaryen to compile an AST to WebAssembly text. Also worth mentioning that Binaryen is the official compiler/toolchain for this purpose which is why I expected more from it.

Currently you use Binaryen to build up a representation of a Wasm module, then call emitText to generate a .wat file from that. With wasm-tools you'd do the same thing via the wasm-encoder crate to generate the bytes corresponding to a .wasm file, and then use the wasmprinter crate to convert from the .wasm format to the .wat format. Alternatively, I believe the walrus crate gives you a somewhat higher-level API to do the same thing, but I haven't used it because it's much heavier-weight.
