The [Substreams-powered subgraphs documentation](/cookbook/substreams-powered-subgraphs/) will show you how to package them for deployment on The Graph.

The [latest Substreams Codegen tool](https://streamingfastio.medium.com/substreams-codegen-no-code-tool-to-bootstrap-your-project-a11efe0378c6) will allow you to bootstrap a Substreams project without any code.

## What is the role of Rust modules in Substreams?

Rust modules are the equivalent of the AssemblyScript mappers in subgraphs. They are compiled to WASM in a similar way, but the programming model allows for parallel execution. They define the sort of transformations and aggregations you want to apply to the raw blockchain data.

Substreams is a powerful blockchain indexing technology, developed for The Graph Network. Substreams enables developers to write Rust modules, composing data streams alongside the community, and provides extremely high-performance indexing by virtue of parallelization, in a streaming-first fashion.

With Substreams, you can extract data from different blockchains (Ethereum, BNB, Solana...) ultra-fast! Then, you can send to data to several locations (a Postgres database, a Mongo database, or a Subgraph).
With Substreams, developers can quickly extract data from different blockchains (Ethereum, BNB, Solana, ect.) and send it to various locations of their choice, such as a Postgres database, a Mongo database, or a Subgraph. Additionally, Substreams packages enable developers to specify which data they want to extract from the blockchain.
