lsp-server
Counted from the Cargo.toml manifests of the 56 indexed repositories that declare lsp-server as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in lsp-server projects. The most distinctive pairings rank first — crates these projects use far more than the average indexed Rust project does, not just crates that are popular everywhere. Each percentage is the share of lsp-server projects that also use it.
