Note: Always use cdylib over dylib for C-compatibility to keep the file size smaller and avoid Rust-specific linking issues. 3. Writing the Code ( src/lib.rs )

By default, Rust compiles libraries into its own internal format ( rlib ). To create a standard Windows DLL, you must specify the cdylib crate type. In your Cargo.toml , add: [lib] crate-type = ["cdylib"] Use code with caution. Copied to clipboard rust_pub.dll

You can find your finished file at target/release/rust_pub.dll . 5. Why Use This? Creating a DLL in Rust allows you to: Note: Always use cdylib over dylib for C-compatibility
