Member Function Documentation

◆ canInferOnFunction()

bool FunctionEffect::canInferOnFunction ( const Decl Callee) const

Return true if the effect is allowed to be inferred on the callee, which is either a FunctionDecl or BlockDecl.

Example: This allows nonblocking(false) to prevent inference for the function.
