It depends on proc-macro2, syn, quote, toml and rustc_version [1]. First three are legitimately expected for any complex enough procedural macros. Toml and rustc_version are apparently for automatic Cargo configuration and fairly harmless by their own. Their transitive dependencies are also not bad: unicode-ident (from proc-macro2), serde, serde_spanned, toml_datetime (from toml), and semver (from rustc_version).
