Why am I getting this error while importing this Rust module?

Goal: Get this to import successfully so I can start using the functions.

Rust Code:

pub use crate::pqcrypto_dilithium::*;

fn main() {
    println!("Hello, world!");
}

Cargo.toml:

[package]
name = "project"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
pqcrypto-dilithium = "0.4.5"

Error:

error[E0432]: unresolved import `crate::pqcrypto_dilithium`
 --> main.rs:1:16
  |
1 | pub use crate::pqcrypto_dilithium::*;
  |                ^^^^^^^^^^^^^^^^^^ maybe a missing crate `pqcrypto_dilithium`?

error: aborting due to previous error

For more information about this error, try `rustc --explain E0432`.

The proper code to use is the following:

pub use pqcrypto_dilithium::*;

fn main() {
    println!("Hello, world!");
}

I think you should not start with crate::.

crate:: means starting looking from this working crate's root.

If you have a module named pqcrypto_dilithium in the project root, then it will work. Just like:

// main.rs/lib.rs
mod pqcrypto_dilithium { ... }
pub use crate::pqcrypto_dilithium::*;

--- 

// main.rs/lib.rs
mod wrap {
  mod pqcrypto_dilithium { ... }
}
// This is not going to work
pub use crate::pqcrypto_dilithium::*;
// Works
pub use crate::wrap::pqcrypto_dilithium::*;

Finally, in your case: pqcrypto_dilithium is a dep, an external crate. So you can not do that.

But you can simply do:

pub use pqcrypto_dilithium::*;
