Enum EmptyOutputPolicy 

pub enum EmptyOutputPolicy {
    KeepEmptySlug,
    UseFallbackSlug(String),
    UseVerbatimFallbackSlug(String),
}

Behavior when the generated slug is empty.

Variants

KeepEmptySlug

Return the empty slug.

UseFallbackSlug(String)

Replace the empty slug with a fallback held to the same rules.

The fallback is checked against the configuration that produced the slug it stands in for — character set, delimiter, dot policy, case and max_slug_chars — not only against the target surface. Without that, an ASCII-only, 80-character configuration could still return an arbitrary-length mixed-case Unicode string and call it validated, and a caller reading “validated” as “matches my SlugConfig” would be wrong in exactly the case they reached for a fallback to avoid.

UseVerbatimFallbackSlug(String)

Replace the empty slug with a fallback inserted exactly as written.

Only the target surface is checked. This exists for a value that must match something already stored — a legacy identifier a caller cannot regenerate — and it means the result may not satisfy the configuration that produced it.
