rustdoc warns main is never used #13894
Description
rustdoc warns that main is never used.
// hello.rs
#![crate_id="hello"]
fn main() {}$ rustdoc hello.rs
hello.rs:3:1: 3:13 warning: code is never used: `main`, #[warn(dead_code)] on by default
hello.rs:3 fn main() {}
^~~~~~~~~~~~
I think rustdoc shouldn't warn about it, because rustc doesn't warn.
$ rustc hello.rs
# no output
If the main is pub, rustdoc doesn't warn about it. Shoulud all mains mark as pub?
// pubhello.rs
#![crate_id="hello"]
pub fn main() {}$ rustdoc pubhello.rs
# no output
$ rustc --version

This is currently intended behavior, rustdoc compiles crates as if it were compiling a library. If you compile
rustdoc --crate-type=dylib hello.rsyou'll get the same warning.rustdoc: Don't have rustc emit warnings
