uv-small-str

crates/uv-small-str/ provides SmallString, a small-string-optimized type used in many hot data structures.

Purpose

Package names, extra names, and hashes are typically short strings, but uv allocates millions of them during a single resolution. A small-string optimization (storing short contents inline rather than on the heap) is a measurable reduction in allocation pressure.
