clippy.toml / .clippy.toml

allows you to configure how Clippy behaves globally across your workspace. By default, Clippy has hundreds of "lints," and some are opinionated. This file lets you dial the strictness up or down to match your project's needs.

# Enforce a maximum cognitive complexity per function
# This measures how "hard" a function is to read (based on if, else, match, and loop nesting). 
# If a function is too complex (score > 25), Clippy will warn you that it's time to refactor.

# You have set this to 512 bytes, meaning anything larger should probably be boxed (on the heap).

# A stylistic check. It encourages you to use 'a' (a char) instead of "a" (a string) 
# when possible, as chars are more efficient.
