Enum rustc_mir::borrow_check::region_infer::values::RegionElement[][src]

pub(crate) enum RegionElement {
    Location(Location),
    RootUniversalRegion(RegionVid),
    PlaceholderRegion(PlaceholderRegion),
}

An individual element in a region value – the value of a particular region variable consists of a set of these elements.

Variants

Location(Location)

RootUniversalRegion(RegionVid)

A universally quantified region from the root universe (e.g., a lifetime parameter).

PlaceholderRegion(PlaceholderRegion)

A placeholder (e.g., instantiated from a for<'a> fn(&'a u32) type).
