Struct Builder 

pub struct Builder { /* private fields */ }

Builder for constructing PGM indices with custom parameters.

Example

use pgm_extra::index::Builder;

let data: Vec<u64> = (0..10000).collect();

let index = Builder::new()
    .epsilon(128)
    .epsilon_recursive(8)
    .build(&data)
    .unwrap();

assert_eq!(index.epsilon(), 128);

Implementations

impl Builder

pub fn new() -> Self

pub fn epsilon(self, epsilon: usize) -> Self

pub fn parallel(self, parallel: bool) -> Self

pub fn build<T: Indexable>(&self, data: &[T]) -> Result<Static<T>, Error>

where T::Key: Ord,

pub fn build_one_level<T: Indexable>( &self, data: &[T], ) -> Result<OneLevel<T>, Error>

where T::Key: Ord,

pub fn build_dynamic<T: Indexable + Ord + Copy>( &self, data: Vec<T>, ) -> Result<Dynamic<T>, Error>

where T::Key: Ord,
