Module binary_format 

HDF5-inspired binary format for simulation checkpoints and time series data.

The OxiFile format stores hierarchical groups of typed datasets with attributes, serialized to a compact binary representation.

Structs

Attribute

A named metadata attribute attached to a dataset or group.

BinaryMesh

A minimal binary triangle mesh representation.

BinaryParticleData

Compact binary storage for particle data (positions + optional scalars).

Dataset

A named, typed, shaped array of raw bytes with optional attributes.

DatasetShape

Describes the shape (dimensions) of a dataset.

Group

A named container that holds datasets, subgroups, and attributes.

OxiFile

Root container for the OxiPhy binary file format.

SimulationCheckpoint

High-level helper for writing physics simulation checkpoint data.

Enums

AttributeValue

Possible values for an attribute.

DataType

Supported element types for datasets.

Endianness

Which byte order a binary stream uses.

FormatVersion

Supported OxiFile format versions.

Functions

read_string

Reads a length-prefixed UTF-8 string, advancing pos.

read_u32

Reads a u32 in little-endian format, advancing pos.

read_u64

Reads a u64 in little-endian format, advancing pos.

rle_compress_f64

Very simple run-length compression for f64 arrays.

rle_decompress_f64

Decompress a run-length encoded f64 array.

write_string

Appends a length-prefixed UTF-8 string (u32 length + bytes).

write_u32

Appends a u32 in little-endian format.

write_u64

Appends a u64 in little-endian format.
