Struct rdir_encoding::IntegerEncoding

pub struct IntegerEncoding;

Integer encoding.

In integer encoding, floating point numbers are converted to integer values by multiplying with a factor and discard everything after the decimal point. Depending on the multiplication factor this can change the precision but with a sufficiently large factor it is lossless. The integer values can then often be compressed with delta encoding which is the main motivation for it.

Examples

use rdir_encoding::IntegerEncoding;

let data = [1.00, 1.00, 0.50];
let encoded = IntegerEncoding::encode(&data, 100).unwrap();
assert_eq!(encoded, vec![100, 100, 50]);

let decoded = IntegerEncoding::decode(&encoded, 100).unwrap();
assert_eq!(decoded, data);

Methods

impl IntegerEncoding

pub fn decode<T>(values: &[T], factor: i32) -> Result<Vec<f32>, RdirError> where
    T: Integer + NumCast + PrimInt, 

Decode and return the decoded data

pub fn encode<T>(values: &[T], factor: i32) -> Result<Vec<i32>, RdirError> where
    T: Float, 

Encode any array of 'T' where T can be any Integer with an desired factor
