Detailed Description

A set of symbols to look up, each associated with a SymbolLookupFlags value.

This class is backed by a vector and optimized for fast insertion, deletion and iteration. It does not guarantee a stable order between operations, and will not automatically detect duplicate elements (they can be manually checked by calling the validate method).

inline

Loop over the elements of this SymbolLookupSet, applying the Body function to each one.

Body must be callable as bool(const SymbolStringPtr &, SymbolLookupFlags). If Body returns true then the element just passed in is removed from the set. If Body returns false then the element is retained.

inline

Loop over the elements of this SymbolLookupSet, applying the Body function to each one.

Body must be callable as Expected<bool>(const SymbolStringPtr &, SymbolLookupFlags). If Body returns a failure value, the loop exits immediately. If Body returns true then the element just passed in is removed from the set. If Body returns false then the element is retained.
