Struct CompressedParams

pub struct CompressedParams { /* private fields */ }

CompactParams contains 2 parameters determining how a CompressedHistogram is stored and interpreted. See CompressedHistogram for a full explanation.

Example

To create your own parameters, use the constructor function

if let Some(cp) = new_compressed_params(2.0, 15) {
    // do something...
} else { }

Implementations

impl CompressedParams

pub fn base(&self) -> f64

pub fn max_exp(&self) -> usize

Trait Implementations

impl Clone for CompressedParams

fn clone(&self) -> CompressedParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompressedParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Histogram<CompressedParams, usize, usize> for CompressedHistogram

fn total(&self) -> usize

returns whichever is greater, the compressed or decompressed size

fn labels( &self, _params: &CompressedParams, ) -> Option<Box<dyn Iterator<Item = usize>>>

If possible, creates and returns an iterator for the labels for which the histogram has frequencies stored.

fn frequency(&self, label: usize, params: &CompressedParams) -> Option<usize>

If possible, returns the frequency of a particular label. The behavior need only be defined if the label is in the set of values returned from labels.
