source · [−]

pub struct ZipfRelation;

Expand description

Generator for relations with Zipf distribution.

Implementations

source

impl ZipfRelation

source

pub fn gen_attr<T: FromPrimitive>(
 attr: &mut [T],
 num_elements: usize,
 exponent: f64
) -> Result<()>

Generates an attribute following the Zipf distribution.

The generated values are sampled from 1 to num_elements (inclusive). Note that the exponent must be greather than 0.

In the literature, num_elements is also called the alphabet size.

source

pub fn gen_attr_par<T: FromPrimitive + Send>(
 attr: &mut [T],
 num_elements: usize,
 exponent: f64
) -> Result<()>

Generates an attribute following the Zipf distribution in parallel.

The generated values are sampled from 0 to num_elements (exclusive). Note that the exponent must be greather than 0.

In the literature, num_elements is also called the alphabet size.
