Struct FillerRowProvider 

pub struct FillerRowProvider { /* private fields */ }

D.4.c: one provider per (session, side) pair.

collect() is synchronous and pure — it reads the session’s published HunkIndex via the lock-free current_hunks() accessor and translates each hunk to zero or more VirtualRows. No background task is needed (the work is O(hunks) and trivial); cf. the inline diff overlay’s DiffOverlayRefreshTask which needs the off-thread render because deletion-block content requires baseline-rope reads + tree-sitter highlight.

Implementations

impl FillerRowProvider

pub fn new(session: Arc<DiffSession>, side: Side) -> Self

pub fn side(&self) -> Side

Trait Implementations

impl Debug for FillerRowProvider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl VirtualRowProvider for FillerRowProvider

fn id(&self) -> ProviderId

A stable id for this provider. Used by the worker to deduplicate registration + route mutation notifications.

fn version(&self) -> u64

Monotonic version counter — the provider bumps it whenever the rows [Self::collect] would emit have changed. The worker uses the combined fingerprint of all providers’ versions to short-circuit on the cache-hit path without paying for the (potentially expensive) collect calls.

fn collect(&self) -> Vec<VirtualRow>

Emit the current set of virtual rows for the associated document.
