Trait FallibleTableRowVersionStore 

pub trait FallibleTableRowVersionStore {
    type Error;

    // Required methods
    fn try_get_table_row_by_logical_id(
        &self,
        collection: &str,
        logical_id: EntityId,
    ) -> Result<Option<UnifiedEntity>, Self::Error>;
    fn try_for_each_table_row_version(
        &self,
        collection: &str,
        logical_id: EntityId,
        visit: impl FnMut(&UnifiedEntity) -> bool,
    ) -> Result<(), Self::Error>;
}

Fallible version access streams candidates instead of retaining a history Vec. Hosts supply only versions of the requested collection/logical identity.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
