unsigned clang::sema::TemplateDeductionInfo::CallArgIndex = 0 |
The index of the function argument that caused a deduction failure.
TDK_DeducedMismatch: this is the index of the argument that had a different argument type from its substituted parameter type.
Definition at line 215 of file TemplateDeduction.h.
TemplateArgument clang::sema::TemplateDeductionInfo::FirstArg |
The first template argument to which the template argument deduction failure refers.
Depending on the result of the template argument deduction, this template argument may have different meanings:
TDK_IncompletePack: this is the number of arguments we deduced for the pack.
TDK_Inconsistent: this argument is the first value deduced for the corresponding template parameter.
TDK_SubstitutionFailure: this argument is the template argument we were instantiating when we encountered an error.
TDK_DeducedMismatch: this is the parameter type, after substituting deduced arguments.
TDK_NonDeducedMismatch: this is the component of the 'parameter' of the deduction, directly provided in the source code.

TemplateParameter clang::sema::TemplateDeductionInfo::Param |
The template parameter to which a template argument deduction failure refers.
Depending on the result of template argument deduction, this template parameter may have different meanings:
TDK_Incomplete: this is the first template parameter whose corresponding template argument was not deduced.
TDK_IncompletePack: this is the expanded parameter pack for which we deduced too few arguments.
TDK_Inconsistent: this is the template parameter for which two different template argument values were deduced.

SmallVector<DeducedPack *, 8> clang::sema::TemplateDeductionInfo::PendingDeducedPacks |
Information on packs that we're currently expanding.
FIXME: This should be kept internal to SemaTemplateDeduction.
Definition at line 220 of file TemplateDeduction.h.
TemplateArgument clang::sema::TemplateDeductionInfo::SecondArg |
The second template argument to which the template argument deduction failure refers.
TDK_Inconsistent: this argument is the second value deduced for the corresponding template parameter.
TDK_DeducedMismatch: this is the (adjusted) call argument type.
TDK_NonDeducedMismatch: this is the mismatching component of the 'argument' of the deduction, from which we are deducing arguments.
FIXME: Finish documenting this.
