In order to use uWebSockets in your Rust application you will have to link the following static libraries to you
binary - libz, libuv, libssl, libcrypto and libstdc++.
It may look something like that in your build.rs file:
rust
println!("cargo:rustc-link-lib=z");
println!("cargo:rustc-link-lib=uv");
println!("cargo:rustc-link-lib=ssl");
println!("cargo:rustc-link-lib=crypto");
println!("cargo:rustc-link-lib=stdc++");
This package is available here - https://crates.io/crates/uwebsockets_rs/versions
