Struct H5partReader 

pub struct H5partReader {
    pub steps: Vec<H5PartStep>,
    pub attributes: HashMap<String, String>,
}

Reader for the H5Part particle trajectory format.

H5Part stores particle data as an HDF5 file with one group per time step (/Step#0, /Step#1, …). This implementation provides a pure-Rust in-memory simulation of the format (no HDF5 C library required).

Fields

steps: Vec<H5PartStep>

Loaded time steps (in order).

attributes: HashMap<String, String>

Metadata attributes stored at file level.

Implementations

impl H5partReader

pub fn new() -> Self

Create an empty reader.

pub fn from_bytes(data: &[u8]) -> Result<Self>

Load a dataset from a byte slice simulating H5Part binary content.

In a real implementation this would call hdf5 crate APIs. Here we parse a simple custom binary format for testing purposes.

pub fn num_steps(&self) -> usize

Return the number of time steps.

pub fn step(&self, idx: usize) -> Option<&H5PartStep>

Return the dataset at a specific step index, if present.

pub fn times(&self) -> Vec<f64>

Return the time values for all steps.

pub fn dataset_names(&self) -> Vec<String>

Return a list of dataset names available in the first step (if any).

pub fn push_step(&mut self, step: H5PartStep)

Add a simulated time step (used for testing / programmatic construction).

pub fn iter_steps(&self) -> impl Iterator<Item = &H5PartStep>

Iterate over all steps.

pub fn step_near(&self, target_time: f64) -> Option<&H5PartStep>

Find the step closest to a given simulation time.

Trait Implementations

impl Clone for H5partReader

fn clone(&self) -> H5partReader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for H5partReader

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

Formats the value using the given formatter.

impl Default for H5partReader

fn default() -> H5partReader

Returns the “default value” for a type.
