Struct SignRandomProjections 

pub struct SignRandomProjections<N: Numeric> { /* private fields */ }

A family of hashers for the cosine similarity.

Implementations

impl<N: Numeric> SignRandomProjections<N>

pub fn new(k: usize, dim: usize, seed: u64) -> Self

Arguments

• k - Number of hyperplanes used for determining the hash. This will also be the hash length.

Trait Implementations

impl<N: Clone + Numeric> Clone for SignRandomProjections<N>

fn clone(&self) -> SignRandomProjections<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'de, N> Deserialize<'de> for SignRandomProjections<N>

where N: Deserialize<'de> + Numeric,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<N> Serialize for SignRandomProjections<N>

where N: Serialize + Numeric,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<N> StepWiseProbe<N, i8> for SignRandomProjections<N>

where N: Numeric,

fn step_wise_probe( &self, q: &[N], budget: usize, hash_len: usize, ) -> Result<Vec<Vec<i8>>>

impl<N: Numeric> VecHash<N, i8> for SignRandomProjections<N>

fn hash_vec_query(&self, v: &[N]) -> Vec<i8>

Create a hash for a query data point.

fn as_step_wise_probe(&self) -> Option<&dyn StepWiseProbe<N, i8>>

If the hasher implements the StepWiseProbe trait it should return Some(self)

fn hash_vec_put(&self, v: &[N]) -> Vec<K>

Create a hash for a data point that is being stored.

fn as_query_directed_probe(&self) -> Option<&dyn QueryDirectedProbe<N, K>>

If the hasher implements the QueryDirectedProbe trait it should return Some(self)
