Struct CompositeKeyExtractor 

Source 
pub struct CompositeKeyExtractor { /* private fields */ }
Expand description

A composite key extractor that combines multiple extractors.

Keys from all extractors are joined with : to form a composite key. If any extractor returns None, that part is omitted.
