Enum FlagClash 

pub enum FlagClash {
    Repeated,
    Contradictory,
    Redundant,
}

Available on crate feature cli only.

The type of clash between flags that a FlagWarning reports. The last value still wins in every case.

The set is closed, and the enum is deliberately not #[non_exhaustive]. Two flags given together are the same flag, two names of one flag, or opposites; no other relation between them exists.

Variants

Repeated

Same flag twice (--format json --format pretty).

Contradictory

Opposite flags (--color always --no-color).

Redundant

Aliases of the same flag (--dry-run --preview).
