◆ Best
| bool clang::OverloadCandidate::Best |
Whether this candidate is the best viable function, or tied for being the best viable function.
For an ambiguous overload resolution, indicates whether this candidate was part of the ambiguity kernel: the minimal non-empty set of viable candidates such that all elements of the ambiguity kernel are better than all viable candidates not in the ambiguity kernel.

◆ BuiltinParamTypes

◆ Function
| FunctionDecl* clang::OverloadCandidate::Function |
