sourcepub fn leased_part_from_exchangeable(
&self,
x: SerdeLeasedBatchPart,
) -> LeasedBatchPart<T>
pub fn leased_part_from_exchangeable( &self, x: SerdeLeasedBatchPart, ) -> LeasedBatchPart<T>
Takes a SerdeLeasedBatchPart
into a LeasedBatchPart
.
sourcepub async fn fetch_leased_part(
&mut self,
part: &LeasedBatchPart<T>,
) -> Result<FetchedBlob<K, V, T, D>, InvalidUsage<T>>
pub async fn fetch_leased_part( &mut self, part: &LeasedBatchPart<T>, ) -> Result<FetchedBlob<K, V, T, D>, InvalidUsage<T>>
Trade in an exchange-able LeasedBatchPart for the data it represents.
Note to check the LeasedBatchPart
documentation for how to handle the
returned value.
