Rust runtime is unable to find symbol "main" of Hello World example

[goldkehlchen]

I am currently trying to run the Hello World example from the documentation in the Rust runtime example. All tools are built from the current revision of the main branch.

Although running with lucet-wasi yields no errors ...

$ wasm32-wasi-clang -Ofast -o hello.wasm hello.c
$ lucetc-wasi -o hello.so hello.wasm
$ lucet-wasi hello.so
Hello world

my attempts at running the same .so file in the Rust runtime fails.

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: SymbolNotFound("main")', src/main.rs:17:31

Is there anything I might have missed?

The documentation is not up to date.

In the Rust code, you should call the function named _start().
