rustfmt

Purpose: Rustfmt formats Rust code according to style guidelines.
Install: The README says to install rustfmt on the stable toolchain with `rustup component add rustfmt`.
Cargo: The `cargo fmt` command formats all binary and library targets in a crate and works with Cargo workspaces.
Input and output: The rustfmt binary can format files or read Rust code from standard input and write formatted output to standard output.
Configuration: Rustfmt accepts configuration in `rustfmt.toml` or `.rustfmt.toml`, with stable and nightly-only unstable options.
Editor integrations: The README lists Vim, Emacs, Sublime Text 3, Atom, Visual Studio Code, IntelliJ, and CLion for running rustfmt from an editor.
CI use: The README describes using `--check` in CI to report formatting differences through an error code.
Limit: comments: Rustfmt does not currently attempt to format comments, though it formats code that contains comments.
Limit: macros: The README says some macro declarations and uses are formatted, while macro declarations and uses are listed among rustfmt’s limitations.
Nightly options: Unstable configuration options are available only on a nightly toolchain and require opt-in.
License: Rustfmt is distributed under both the MIT License and Apache License 2.0.
Security contact: The Rust Security Response Working Group handles vulnerability reports and security issues for rust-lang organization repositories.
Style stability: The Rust Edition Guide describes a formatting stability guarantee intended to avoid noisy formatting changes when updating the Rust toolchain.
Direct use: The rustfmt binary formats files in place or reads Rust code from standard input and writes formatted code to standard output.
