# Description Lint: `clippy::uninlined_format_args` More readable in most situations. (May be slightly confusing for modifier format strings https://doc.rust-lang.org/std/fmt/index.html#formatting-parameters) Alternative to #7865 # User-Facing Changes None intended # Tests + Formatting (Ran `cargo +stable clippy --fix --workspace -- -A clippy::all -D clippy::uninlined_format_args` to achieve this. Depends on Rust `1.67`)
