Enum rustc_infer::infer::error_reporting::TyCategory[−][src]

pub enum TyCategory {
    Closure,
    Opaque,
    Generator(GeneratorKind),
    Foreign,
}
Expand description

This is a bare signal of what kind of type we’re dealing with. ty::TyKind tracks extra information about each type, but we only care about the category.

Variants

Closure
Opaque
Generator(GeneratorKind)
Foreign
