Struct DeltaCheckpoint 

pub struct DeltaCheckpoint {
    pub base_step: u64,
    pub target_step: u64,
    pub changed_indices: Vec<usize>,
    pub positions: Vec<[f64; 3]>,
    pub velocities: Vec<[f64; 3]>,
}

Delta checkpoint that records only particles that changed since a base state.

Fields

base_step: u64

Step number of the base state.

target_step: u64

Step number of this delta.

changed_indices: Vec<usize>

Indices of changed particles.

positions: Vec<[f64; 3]>

New positions for changed particles.

velocities: Vec<[f64; 3]>

New velocities for changed particles.

Implementations

impl DeltaCheckpoint

pub fn compute( base_step: u64, target_step: u64, base: &SimulationState, target: &SimulationState, tol: f64, ) -> Self

Compute a delta between base and target states.

A particle is considered changed if any position or velocity component differs by more than tol.

pub fn num_changed(&self) -> usize

Number of changed particles.

pub fn byte_size(&self) -> usize

Serialised size in bytes (approximate).

pub fn apply(&self, base: &SimulationState) -> SimulationState

Apply this delta to base, returning a new reconstructed state.

Trait Implementations

impl Clone for DeltaCheckpoint

fn clone(&self) -> DeltaCheckpoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeltaCheckpoint

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

Formats the value using the given formatter.
