Trait lsh_rs::VecHash

pub trait VecHash<N, K> {
    fn hash_vec_query(&self, v: &[N]) -> Vec<K>;

    fn hash_vec_put(&self, v: &[N]) -> Vec<K> { ... }
    fn as_query_directed_probe(&self) -> Option<&dyn QueryDirectedProbe<N, K>> { ... }
    fn as_step_wise_probe(&self) -> Option<&dyn StepWiseProbe<N, K>> { ... }
}

Implement this trait to create your own custom hashers. In case of a symmetrical hash function, only hash_vec_query needs to be implemented.

Required methods

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

Create a hash for a query data point.

Provided methods

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)

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

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