perf: optimize linker path processing and validation#318
Conversation
- Refactored `for_each_nested_glob_match` to use a more efficient platform-agnostic path string construction, avoiding multiple allocations per file during discovery. - Eliminated redundant `Vec` allocations in `ensure_safe_destination` by iterating over path components directly. - Added performance comments to document optimizations and their expected impact.

This change optimizes two allocation hot spots in the
linker.rsmodule.The first optimization is in
for_each_nested_glob_match, which is used during recursive file discovery forNestedGlobtargets. It replaces a chain ofcomponents().map().collect().join("/")with a more directto_string_lossy()and a conditional backslash replacement. On Unix, this is now zero-allocation, and on Windows, it performs exactly one allocation.The second optimization is in
ensure_safe_destination, which is called for every target. It removes a redundantcollect::<Vec<_>>()call and instead iterates over thepath.components()iterator directly.Both changes reduce heap pressure and improve the overall efficiency of the synchronization engine, especially in large monorepos with many files.
