Enum MetaSearch 

pub enum MetaSearch<'a> {
    NoMetadata,
    Hits(&'a [MetaEntry]),
}

The result of a search that may not have happened.

Hits(&[]) means searched, found nothing. NoMetadata means there was nothing to search. Same absence of results, different fact — and no method here flattens one into the other.

Variants

NoMetadata

Hits(&'a [MetaEntry])

Implementations

impl<'a> MetaSearch<'a>

pub fn hits(&self) -> Option<&'a [MetaEntry]>

The hits, or None when the archive had no index. Naming the absent case is the point.

pub fn found_any(&self) -> bool

true only for a real search that returned real rows.
