Struct Hdf5FileImage 

pub struct Hdf5FileImage {
    pub version: u8,
    pub group_segments: Vec<(String, String)>,
    pub dataset_segments: Vec<(String, String, Vec<usize>, Vec<f64>)>,
    pub attr_segments: Vec<(String, String, String, String)>,
}

A byte-oriented image of an in-memory HDF5 file.

Encodes groups, datasets and attributes into a compact binary representation for testing checkpoint / restart round-trip workflows.

Fields

version: u8

Version tag.

group_segments: Vec<(String, String)>

Serialised group segments: (path, attr_json).

dataset_segments: Vec<(String, String, Vec<usize>, Vec<f64>)>

Serialised dataset segments: (group_path, name, shape, flat_f64).

attr_segments: Vec<(String, String, String, String)>

Serialised attribute segments: (group, name, attr_name, value_str).

Implementations

impl Hdf5FileImage

pub fn from_file(file: &Hdf5File) -> Self

Build an image from an Hdf5File.

Only datasets containing f64 data are captured; other dtypes are skipped.

pub fn restore_to_file(&self, file: &mut Hdf5File) -> Hdf5Result<()>

Restore datasets from this image into a (possibly empty) Hdf5File.

pub fn n_datasets(&self) -> usize

Total number of dataset segments in the image.

Trait Implementations

impl Clone for Hdf5FileImage

fn clone(&self) -> Hdf5FileImage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hdf5FileImage

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

Formats the value using the given formatter.
