Describe what you are looking for

index_dense_gt has a configuration item that controls key-to-vector lookup table generation: index_dense_config_t::enable_key_lookups.

When you try to build an usearch index, you can set index_dense_config_t::enable_key_lookups to false by passing index_dense_config_t instance to the index_dense_gt::make() function.

On the other hand, when trying to load index from a serialized buffer, you have to default initialize index_dense_gt, and then you call index_dense_gt::view(). There is no way to pass custom index_dense_config_t to index_dense_gt. Of course you can pass config by calling index_dense_gt::make(). But here's the thing: if you create an instance of index_dense_gt by calling index_dense_gt::make(), you cannot load a serialized index using it. Because index_dense_gt::make() function creates an instance of index_gt and sets the pointer to it in index_dense_gt::typed_, which leads to an error 'No available threads to lock' from index_dense_gt::view().

We absolutely need a way to set enable_key_lookups false even when we try to load index from serialized buffer.
