Enum AbortKind 

#[non_exhaustive]
pub enum AbortKind {
    SingleOpenInterval,
    RecordedAtRegression,
    DeleteOutsideArchive,
    CrossLineage,
    BranchImmutable,
    BranchesFrozen,
    NotAGuard,
}

A guard abort recognised by its message (§4.3).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SingleOpenInterval

RecordedAtRegression

DeleteOutsideArchive

CrossLineage

A concept id already held by a different lineage (v12, §15.2, D-214).

BranchImmutable

An UPDATE that would move a concept between lineages (v12, D-214).

BranchesFrozen

Any write to branches other than an insert (v12, §15.2).

NotAGuard

Not one of our guards — an ordinary engine error.
