Method vector_addition

src/darkbird/storage_vector.rs:289–298

Performs element-wise addition of two vectors stored in the darkbird storage. The vectors are identified by their keys (IDs). The function returns the result of the addition as a new vector. The vectors must have the same number of dimensions. # Arguments `key1` - The key (ID) of the first vector to be added. `key2` - The key (ID) of the second vector to be added. # Returns An `Option` contai

(&self, vec_id1: &str, vec_id2: &str)
