Enum VectorQuantization 

#[non_exhaustive]
pub enum VectorQuantization {
    NoQuant,
    Q8,
    Bin,
}

Available on crate feature vector-sets only.

Quantization options for vector storage

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoQuant

In the first VADD call for a given key, NOQUANT forces the vector to be created without int8 quantization, which is otherwise the default.

Q8

Forces the vector to use signed 8-bit quantization. This is the default, and the option only exists to make sure to check at insertion time that the vector set is of the same format.

Bin

Forces the vector to use binary quantization instead of int8. This is much faster and uses less memory, but impacts the recall quality.
