Struct foundationdb::transaction::GetRangeResult

pub struct GetRangeResult { /* private fields */ }

Represents the data of a Transaction::get_range. The result might not contains all results specified by Transaction::get_range. A caller can test if the result is complete by either checking GetRangeResult::key_values().more() is true, or checking GetRangeResult::next is not None. If a caller wants to fetch all matching results, they should call Transcation::get_range with following RangeOption returned by GetRangeResult::next. The caller might want to use Transaction::get_ranges which will fetch all results until it finishes.

Implementations

impl GetRangeResult

pub fn transaction(&self) -> Transaction

Returns a clone of the Transaction this get is a part of

pub fn key_values(&self) -> KeyValues<'_>

Returns the values associated with this get

pub fn next(&self) -> Option<RangeOption>

Returns None if all results are returned, and returns Some(_) if there are more results to fetch. In this case, user can fetch remaining results by calling Transaction::get_range with returned RangeOption.
