Struct `MapFailurePersistence`

pub struct MapFailurePersistence { pub map: BTreeMap<&'static str, BTreeSet<PersistedSeed>> }

Failure persistence option that loads and saves seeds in memory on the heap. This may be useful when accumulating test failures across multiple TestRunner instances for external reporting or batched persistence.

Fields

map: BTreeMap<&'static str, BTreeSet<PersistedSeed>>: Backing map, keyed by source_file.
