mold ships as a Rust linker, reporting 4.9x over lld at the median

Sources: mold repository, HN submission
Summary: The repository builds with Cargo and a stable Rust toolchain, and the documented build still requires Git and a C compiler such as GCC or Clang alongside it. The README carries no date and no release note, so the switch is dated only by the state of the page as read, and the same README attributes the 4.9x median speedup over lld to the project's own August 2026 benchmarks on builds from 2026-08-28, which is not reproduced here.
Why it matters: Packaging or vendoring mold adds a stable Rust toolchain to the build requirements rather than replacing the C toolchain, which the instructions still list.
