Struct Extractor 

Source 
pub struct Extractor<L: Language, CF: CostFunction<L>> { /* private fields */ }
Expand description

An object used for quickly extracting terms (i.e. RecExprs) using a given CostFunction.

Creating an Extractor will setup an extraction-table which then allows you to extract terms from many e-classes efficiently. It is most useful when doing “bulk” extractions for many classes.
