Enum rustc_borrowck::region_infer::values::RegionElement

source · [−]

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

Expand description

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

Variants

`Location(Location)`

A point in the control-flow graph.

`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).
