Expand description

Results concerning an operation to remove many keys.

Fields§

§maybe_cursor: Option<Vec<u8, Global>>

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.
