Struct SkipPolicy 

pub struct SkipPolicy { /* private fields */ }

Which directories a snapshot walks past.

A NAME alone is only a guess: plenty of projects keep real, irreplaceable source in a folder called build/, and Go projects commit vendor/. Skipping those by name would mean undo could never bring them back — a data-loss bug in a tool that exists to prevent data loss.

So a directory is skipped only when BOTH hold:

1. its name is on the list (it is the KIND of thing that gets rebuilt), and
2. git already ignores it (the project itself declares it disposable).

Gitignored-but-not-a-build-dir (.env, a local database) is captured — that is precisely what git does NOT protect and what doover is for.

Outside a git repo there is no disposability signal, so the name list is all there is; the fallback is name-only. Every other uncertainty (no repo root, unreadable .gitignore, a nested ignore we did not load) resolves toward CAPTURING: being slower is recoverable, being lossy is not.

Implementations

impl SkipPolicy

pub fn new(names: Vec<String>, repo_root: Option<&Path>) -> Self

repo_root = the enclosing git repository, if any.

pub fn none() -> Self

Skip nothing (used by plain snapshot() and by tests).
