tensogram

The primary Tensogram library for fast binary N-tensor message format.

This crate provides encode, decode, file I/O, and streaming capabilities for scientific data. It supports self-describing messages with CBOR metadata, multiple tensors per message, partial decode, and remote access to cloud storage.

Usage

use tensogram::{encode, decode, EncodeOptions, DecodeOptions};

let message = encode(&meta, &[(&desc, &data)], &EncodeOptions::default())?;
let (_, objects) = decode(&message, &DecodeOptions::default())?;

// File API with partial decode
use tensogram::{TensogramFile, decode_range};

let file = TensogramFile::open("data.tgm")?;
let slice = decode_range(&file, 0, &[0..100, 50..150])?;
