Struct NvimHost 

pub struct NvimHost { /* private fields */ }

Host-side Nvim state: the only thing the host must track itself is the pending-Z flag for the ZZ/ZQ two-key sequence.

Implementations

impl NvimHost

pub fn new() -> Self

pub fn handle_key(&mut self, nvim: &NvimBackend, key: &KeyEvent, tx: &AppTx)

Apply one key to the Nvim backend: classify, update the pending-Z flag, then forward / emit as the decision dictates.

The snapshot Mutex (shared with the reverse-refresh task) is locked only when the decision actually consults mode/cmdline — see needs_snapshot. Ordinary keystrokes (insert-mode typing, the pending-Z second key) take the lock-free path: no lock, no clone.

pub fn frame_sync( &self, nvim: &NvimBackend, width: u16, height: u16, ) -> Option<((usize, usize), (usize, usize))>

Per-frame sync: resize nvim to the editor area, then read the snapshot’s active visual selection.

The revision is deliberately NOT read here. content_gen is owned by the reverse-refresh task in backend.rs, which bumps it only when snap.lines actually diffs; the frame snapshot (snapshot_from_backend) derives the editor’s revision from it under a single lock, and the editor’s Revisions adopts that value. Navigation keystrokes don’t change lines, so they don’t bump content_gen — an in-flight autosave’s revision token stays valid across cursor movement.

Trait Implementations
