Trait Implementations

impl BackendHandle for NoopBackend

fn add_dir(&self, _dir: &Path) -> bool

Arm a watch on a directory about to be enumerated. false means watch descriptors are exhausted: the caller closes the root rather than serve a mirror with a silently stale subtree in it.

fn watch_outside(&self, _dir: &Path)

Arm a directory outside the synced tree, because it holds an ignore source the matcher consulted. Unlike BackendHandle::add_dir this is not covered by a recursive root watch, so every filtered root needs it however the tree itself is watched.

fn remove_dir(&self, _dir: &Path)

Disarm a directory and everything under it — deleted, or newly excluded.

fn retain_dirs(&self, _keep: &dyn Fn(&Path) -> bool)

Disarm every armed directory keep rejects, after a full rescan replaces the index wholesale.
