**B**inary E**n**coding (DBN) is an extremely fast message encoding and storage format for normalized market data.\nThe DBN specification includes a simple, self-describing metadata header and a fixed set of struct definitions, which enforce a standardized way to normalize market data.\n\nAll official Databento client libraries use DBN under the hood, both as a data interchange format and for in-memory representation of data.\nDBN is also the default encoding for all Databento APIs, including live data streaming, historical data streaming, and batch flat files.\n\nThis repository contains both  libraries and a CLI tool for working with DBN files and streams.\nPython bindings for `dbn` are provided in the `databento_dbn` package.\n\nFor more details, read our [introduction to DBN](https://databento.com/docs/standards-and-conventions/databento-binary-encoding).\n\n## Features\n\n- Performant binary encoding and decoding\n- Highly compressible with Zstandard\n- Extendable fixed-width schemas\n\n## Usage\n\nSee the respective READMEs for usage details:\n- [`dbn`](rust/dbn/README.md): Rust library crate\n- [`dbn-cli`](rust/dbn-cli/README.md): CLI crate providing a `dbn` binary\n- [`databento-dbn`](python/README.md): Python package\n\n## License\n\nDistributed under the [Apache 2.0
