Struct frame_support::storage::child::MultiRemovalResults
pub struct MultiRemovalResults {
pub maybe_cursor: Option<Vec<u8>>,
pub backend: u32,
pub unique: u32,
pub loops: u32,
}
Expand description
Results concerning an operation to remove many keys.
Fields§
§maybe_cursor: Option<Vec<u8>>
A continuation cursor which, if Some
must be provided to the subsequent removal call.
If None
then all removals are complete and no further calls are needed.
backend: u32
The number of items removed from the backend database.
unique: u32
The number of unique keys removed, taking into account both the backend and the overlay.
loops: u32
The number of iterations (each requiring a storage seek/read) which were done.
