When building Rust packages that provide libraries but no executable binaries, `cargo install` doesn't do anything; you need to use `cargo build` and install any libraries manually. See e.g. rust-lang/cargo#8294. Unfortunately, Homebrew's Rubocop "use cargo install *std_cargo_args" rule, as currently written, blocks all invocations of `cargo build`. This commit changes that rule to exclude invocations of `cargo build` that use the `--lib` argument (`--lib` specifies to Cargo that a package's library targets should be built). This will enable library packages to be built while retaining the "use cargo install *std_cargo_args" message for the more common case when a Rust package provides executable binaries.

This directory contains all the code run by the official brew command in Homebrew and all formulae (package descriptions) in taps (repositories containing formulae) in Taps subdirectories.
