...Since command line input always arrives as plain text, custom types like LogLevel need a way to be matched against text. Deriving ValueEnum tells Clap which strings map to which variants, by default the lowercased variant names, so --log-level warn selects LogLevel::Warn. Any other value is rejected before...

The rust_2024_guarded_string_incompatible_syntax lint will identify any tokens that match the reserved syntax, and will suggest a modification to insert spaces where necessary to ensure the tokens continue to be parsed separately.
The lint is part of the rust-2024-compatibility lint group which is...
