Struct VtkCompression 

Source 
pub struct VtkCompression;
Expand description

Provides simple run-length encoding for f64 data (for illustration).

Implementations§

Source§

impl VtkCompression

Source

pub fn rle_encode_f64(data: &[f64]) -> Vec<(f64, usize)>

Run-length encode a slice of f64 values.

Consecutive equal values are stored as (value, count) pairs.

Source

pub fn rle_decode_f64(runs: &[(f64, usize)]) -> Vec<f64>

Decode RLE-encoded f64 data back to a flat vector.

Source

pub fn compression_ratio(original_len: usize, n_runs: usize) -> f64

Compute compression ratio: original_len / encoded_pairs.

Source

pub fn delta_encode_u8(data: &[u8]) -> (Vec<i8>, u8)

Losslessly encode a u8 slice using a simple byte-pair delta encoding.

Returns (delta_bytes, first_value). Decode with delta_decode_u8.

Source

pub fn delta_decode_u8(deltas: &[i8], first: u8) -> Vec<u8> ⓘ

Decode delta-encoded bytes.
