Enum VectorEncryption 

pub enum VectorEncryption {
    None,
    Dcpe,
    ClientSide,
}

How a collection’s vectors are encrypted (ADR-0031, ADR-0032). Encryption is always client-side — the server never holds the key. Defaults to VectorEncryption::None. The variants sit on Quiver’s encrypted-search spectrum, from fastest to most confidential:

• None: plaintext vectors; the server ranks and sees everything (the default).
• Dcpe: experimental property-preserving encryption; the server ranks ciphertexts but the approximate distance-comparison relation leaks by design. L2 only; not semantically secure (ADR-0031).
• ClientSide: semantically secure (IND-CPA) opaque AEAD ciphertext; the server stores blobs it cannot read and does no distance math, so the client fetches and ranks locally (ADR-0032).

The discriminants are chosen so a descriptor written when this flag was a bool encrypted_vectors decodes unchanged: false (byte 0) is None and true (byte 1) is Dcpe — no data migration.

Variants

None

Plaintext vectors; the server ranks (the default).

Dcpe

Experimental DCPE ciphertext (ADR-0031): the server ranks, the approximate distance-comparison relation leaks by design, L2 only, not semantically secure.

ClientSide

Semantically secure opaque AEAD ciphertext (ADR-0032): the server stores blobs it cannot read and does no distance math; the client ranks locally.

Trait Implementations

impl Clone for VectorEncryption

fn clone(&self) -> VectorEncryption

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for VectorEncryption

impl Debug for VectorEncryption

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for VectorEncryption

fn default() -> VectorEncryption

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VectorEncryption

fn deserialize<__D>( __deserializer: __D, ) -> Result<VectorEncryption, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for VectorEncryption

impl PartialEq for VectorEncryption

fn eq(&self, other: &VectorEncryption) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for VectorEncryption

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
