Trait ListableSubstateDatabase

pub trait ListableSubstateDatabase {
    // Required method
    fn list_partition_keys(
        &self,
    ) -> Box<dyn Iterator<Item = DbPartitionKey> + '_>;
}

A partition listing interface between Track and a database vendor.

Required Methods

fn list_partition_keys(&self) -> Box<dyn Iterator<Item = DbPartitionKey> + '_>

Iterates over all partition keys, in an arbitrary order.

Alternatives

You likely want to use the read_partition_keys method instead, which returns an unmapped key. This is available if the trait ListableSubstateDatabaseExtensions is in scope.
