Enum rustc_borrowck::region_infer::RegionRelationCheckResult

source · [−]

enum RegionRelationCheckResult {
    Ok,
    Propagated,
    Error,
}

Expand description

When we have an unmet lifetime constraint, we try to propagate it outward (e.g. to a closure environment). If we can’t, it is an error.

Variants

`Ok`

`Propagated`

`Error`
