Implement https://github.com/rust-lang/rust-clippy/issues/8368 - a new lint to inline format arguments such as `print!("{}", var)` into `print!("{var}")`. code | suggestion | comment ---|---|--- `print!("{}", var)` | `print!("{var}")` | simple variables `print!("{0}", var)` | `print!("{var}")` | positional variables `print!("{v}", v=var)` | `print!("{var}")` | named variables `print!("{0} {0}", var)` | `print!("{var} {var}")` | aliased variables `print!("{0:1$}", var, width)` | `print!("{var:width$}")` | width support `print!("{0:.1$}", var, prec)` | `print!("{var:.prec$}")` | precision support `print!("{:.*}", prec, var)` | `print!("{var:.prec$}")` | asterisk support code | suggestion | comment ---|---|--- `print!("{0}={1}", var, 1+2)` | `print!("{var}={0}", 1+2)` | Format string uses an indexed argument that cannot be inlined. Supporting this case requires re-indexing of the format string. changelog: [`uninlined_format_args`]: A new lint to inline format arguments, i.e. `print!("{}", var)` into `print!("{var}")`
