[−][src]Struct c2_histograms::standard::StandardHistogram
StandardHistogram
is a naive implementation of a histogram with no optimizations.
It has optimal performance since it stores an exact count for exact labels, but it can take
an arbitrary amount of space. It uses a library HashMap to store label-frequency pairs, and
can be instantiated with one using the create_standard_histogram
function.
StandardHistogram
is associated with NullParams.
Example
To create, pass a HashMap to the constructor function:
let mut data = HashMap::new(); data.insert(1, 40); data.insert(3, 15); data.insert(50, 1); let histogram :StandardHistogram = create_standard_histogram(data);
Implementations
impl StandardHistogram
[src]
pub fn to_compact(&self, cp: &CompactParams) -> Option<CompactHistogram>
[src]
If possible, creates a CompactHistogram
of this histogram.
Example
use c2_histograms::c2::{CompactHistogram, new_compact_params, CompactParams}; let histogram : StandardHistogram = create_standard_histogram(data); let cp : CompactParams = new_compact_params(3.5, 8, 8).unwrap(); let compact_histogram : CompactHistogram = histogram.to_compact(&cp).unwrap();
pub fn to_compressed(
&self,
cp: &CompressedParams
) -> Option<CompressedHistogram>
[src]
&self,
cp: &CompressedParams
) -> Option<CompressedHistogram>
If possible, creates a CompressedHistogram
of this histogram.
Example
use c2_histograms::c2::{CompressedHistogram, new_compressed_params, CompressedParams}; let histogram : StandardHistogram = create_standard_histogram(data); let cp : CompressedParams = new_compressed_params(1.5, 255).unwrap(); let compact_histogram : CompressedHistogram = histogram.to_compressed(&cp).unwrap();
pub fn to_c2(&self, c2p: &C2Params) -> Option<C2Histogram>
[src]
If possible, creates a C2Histogram
of this histogram
Example
use c2_histograms::c2::{CompactHistogram, new_compact_params, CompactParams, new_c2_params, C2Params, C2Histogram}; use c2_histograms::c2::{CompressedHistogram, new_compressed_params, CompressedParams}; let histogram : StandardHistogram = create_standard_histogram(data); let cp1 : CompactParams = new_compact_params(3.5, 8, 8).unwrap(); let cp2 : CompressedParams = new_compressed_params(1.5, 255).unwrap(); let cp : C2Params = new_c2_params(cp1, cp2); let compact_histogram : C2Histogram = histogram.to_c2(&cp).unwrap();
