Enum rustc_middle::ty::abstract_const::FailureKind

source · [−]

pub enum FailureKind {
    MentionsInfer,
    MentionsParam,
    Concrete,
}

Variants

`MentionsInfer`

The abstract const still references an inference variable, in this case we return TooGeneric.

`MentionsParam`

The abstract const references a generic parameter, this means that we emit an error here.

`Concrete`

The substs are concrete enough that we can simply try and evaluate the given constant.
