Enum Topology 

pub enum Topology {
    Bin,
    Mod,
}

How the split file sits in the module tree — fixes the sibling path prefix and where sub-module files go. Re-export visibility is per part in both topologies: pub use when the part has a public item (preserving the crate’s public API), else pub(crate) use.

Variants

Bin

A binary or library crate root (main.rs, lib.rs): siblings reached via crate::, fn main (if any) kept at the root.

Mod

A nested library module (foo/mod.rs, or a plain foo.rs file module): sub-modules reached via super:: and re-exported with a single per-module glob — pub use to preserve a public API, else pub(crate) use. A plain foo.rs file module resolves mod bar; to foo/bar.rs, so its sub-modules are written into a foo/ subdir.
