fmt

name	fmt
description	Check or apply rustfmt formatting across the workspace. Use this when asked to format code, check formatting, or fix rustfmt issues.

Always use cargo xtask fmt to format or check formatting in this project — never bare cargo fmt.

Basic usage

# Check formatting (default — exits non-zero if any file would change)
cargo xtask fmt

# Apply formatting in place
cargo xtask fmt --apply

When to use each mode

Goal	Command
CI formatting gate	cargo xtask fmt
Fix formatting locally	cargo xtask fmt --apply

Notes

• Without --apply the command runs cargo fmt --all --check, which is the correct mode for CI.
• Always run cargo xtask fmt --apply before committing to avoid CI failures.
