Struct ValidationResultMethodVersions 

pub struct ValidationResultMethodVersions {
    pub flatten: FeatureVersion,
    pub merge_many: FeatureVersion,
}

Versions of the aggregator methods on [crate::validation::ValidationResult] (flatten, merge_many).

Issue #2867: in v0 the aggregators returned Some(empty_vec) when no per-item input contributed any data, which caused validating-state-transition-for-free — empty-action batches were treated as paid (and stayed in the block) instead of unpaid (removed in prepare_proposal). v1 returns None in that case so the result correctly flows down the unpaid path.

Fields

flatten: FeatureVersion

merge_many: FeatureVersion
