Struct XtcEncoder 

pub struct XtcEncoder;

Minimal XTC-like lossy compression for particle positions.

Positions are quantised to integer multiples of 1e-3 nm (the default XTC precision) and stored as big-endian i32 values, preceded by a 4-byte particle count.

Implementations

impl XtcEncoder

pub fn new() -> Self

Create a new encoder.

pub fn compress_frame(positions: &[[f32; 3]]) -> Vec<u8>

Compress positions into a byte buffer using integer quantisation.

The precision is fixed at 1000 (i.e. 3 decimal places in nm units).

pub fn decompress_frame(buf: &[u8], n: usize) -> Option<Vec<[f32; 3]>>

Decompress a byte buffer produced by compress_frame.

Returns None if buf is malformed.

Trait Implementations

impl Debug for XtcEncoder

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

Formats the value using the given formatter.

impl Default for XtcEncoder

fn default() -> XtcEncoder

Returns the “default value” for a type.
