Hiro-Chiba/fileview v2.4.0

v2.4.0 - Performance Pass

on GitHub

Performance-focused release. Internal rendering and event-loop
changes reduce CPU and stat() overhead in everyday use.

Highlights

• Dirty-frame rendering skips redraws on idle frames
• Cached visible entries avoid repeated tree traversal
• Async preview worker keeps the UI responsive during heavy previews

Added

• release-fast Cargo profile for runtime-optimized builds (cargo install fileview --profile release-fast)

Changed

• File watcher syncs only when the expanded directory set changes
• Status bar metadata is cached to eliminate repeated stat() calls
• Sort keys are precomputed once on tree load instead of per comparison
• Heavy preview generation (syntax highlight, hex dump) moved off the UI thread
• Incremental fuzzy narrowing reuses prior matches when the query extends a prefix
• Dependency refresh: petgraph 0.8.3 (#144), toml 1.0.1 (#143), rust-minor-patch group (#146), Cargo.lock (#147)
