Struct VectorMask 

pub struct VectorMask { /* private fields */ }

A secret permutation of [0, dim).

Implementations

impl VectorMask

pub fn derive(passphrase: &[u8], salt: &[u8], dim: usize) -> Result<Self>

Derive the mask for dim coordinates from a passphrase and salt.

The same (passphrase, salt, dim) always yields the same mask, so every client of one collection must share the salt. The salt is not secret.

pub fn dimensions(&self) -> usize

pub fn apply(&self, vector: &EntangledHVec) -> Result<EntangledHVec>

Mask a vector. Fails if its dimension differs from the mask’s.

pub fn invert(&self, masked: &EntangledHVec) -> Result<EntangledHVec>

Recover the original vector from a masked one.

Trait Implementations

impl Drop for VectorMask

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
