The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Rust + WASM + Typescript [+ React]
There are many options, but what worked best for me is compiling with cargo-wasi and loading the resulting Wasm file with browser_wasi_shim. Using wasm32-wasi instead of wasm32-unknown-unknown requires a bit more work (the communication with JS has to be set up manually), but gives the flexibility of having just a Wasm file that can be dropped in and loaded dynamically. (There's wit-bindgen for generating wrapping code according to an interface definition but I didn't have much success with it.)

Can I force rust to treat stdlib like other crates in terms of linkage?
I don't know which symbols are missing, haven't done anything on the llvm level. But I had the same problems creating a no-std no-libc application, if you add https://github.com/rust-lang/compiler-builtins as a dependency you should get all the symbols you need, std uses the same but if you want to use it outside of std you'll need nightly since it uses a lot a nightly features. It might apply to your case as well.

rustc + avr = lovelove back again!
I'm glad to inform y'all that after a year, the infamous LLVM ERROR: Not supported instr bug¹ has been finally fixed and today's nightly can compile for AVR back again! 😎

Porting Rust's std to rustix
Then, some of the non-trivial things that are needed are already implemented and maintained in other crates, like memcpy and friends in compiler-builtins, all the math routines in libm and malloc in dlmalloc.

What are some alternatives?
When comparing cargo-wasi and compiler-builtins you can also consider the following projects:
wee_alloc - The Wasm-Enabled, Elfin Allocator
rt-thread - RT-Thread is an open source IoT real-time operating system (RTOS).
WASI - WebAssembly System Interface
wasi - Experimental WASI API bindings for Rust
relibc - Mirror of https://gitlab.redox-os.org/redox-os/relibc
browser_wasi_shim - A WASI shim for in the browser
rustix - Safe Rust bindings to POSIX-ish APIs
wasmtime - A fast and secure runtime for WebAssembly
libm - A port of MUSL's libm to Rust.
lol_alloc - Like wee_alloc, but smaller since I used skinnier letters in the name.
avr-device - Register access crate for AVR microcontrollers
