- This member is added by an implicit conversion from Extractor[A, B] toExtractor.OptionFunctionToExtractor[A, B] performed by method OptionFunctionToExtractor in com.thoughtworks.LowPriorityExtractor.
- Shadowing
- This implicitly inherited member is ambiguous. One or more implicitly inherited members have similar signatures, so calling this member may produce an ambiguous implicit conversion compiler error.
To access this member you can use a type ascription:(extractor: Extractor.OptionFunctionToExtractor[A, B]).extract
