Enum CppTemplateResolutionError 

pub enum CppTemplateResolutionError {
    AliasCycle {
        alias: CodeUnit,
    },
    ArgumentBinding,
    Substitution,
    PrimarySelection,
    AmbiguousSpecialization {
        candidates: Vec<CodeUnit>,
    },
}

Why template-argument resolution failed. Definition diagnostics render each mode differently; graph scans only care that the resolution is unproven and match Err(_).

Variants

AliasCycle

A template alias expansion revisited alias.

Fields

alias: CodeUnit

ArgumentBinding

The explicit arguments do not bind to the declared template parameters.

Substitution

Bound arguments do not substitute into the alias target’s arguments.

PrimarySelection

No visible primary template declaration could be selected and reconciled for the specialization family.

AmbiguousSpecialization

More than one applicable specialization remains and none is strictly more specialized than every other candidate.

Fields

candidates: Vec<CodeUnit>
