Struct tidb_query_common::storage::test_fixture::FixtureStorage

pub struct FixtureStorage {
    data: Arc<BTreeMap<Vec<u8>, Result<Vec<u8>, Box<dyn Send + Sync + Fn() -> StorageError>>>>,
    data_view_unsafe: Option<Range<'static, Vec<u8>, Result<Vec<u8>, Box<dyn Send + Sync + Fn() -> StorageError>>>>,
    is_backward_scan: bool,
    is_key_only: bool,
}

A Storage implementation that returns fixed source data (i.e. fixture). Useful in tests.
