## What is Swiftide?
Swiftide is a Rust library for building LLM applications, enabling fast data ingestion, transformation, and indexing for effective querying and prompt injection, known as Retrieval Augmented Generation. It provides flexible building blocks for creating various agents, allowing rapid development from concept to production with minimal code.
### High level features
- Build fast, streaming indexing and querying pipelines
- Easily build agents, mix and match with previously built pipelines
- A modular and extendable API, with minimal abstractions
- Integrations with popular LLMs and storage providers
- Ready to use pipeline transformations

## Examples
Indexing a local code project, chunking into smaller pieces, enriching the nodes with metadata, and persisting into [Qdrant](https://qdrant.tech):
```rust
indexing::Pipeline::from_loader(FileLoader::new(".").with_extensions(&["rs"]))
.with_default_llm_client(openai_client.clone())
.filter_cached(Redis::try_from_url(
redis_url,
"swiftide-examples",
)?)
.then_chunk(ChunkCode::try_for_language_and_chunk_size(
"rust",
10..2048,
)?)
.then(MetadataQACode::default())
.then(move |node| my_own_thing(node))
.then_in_batch(Embed::new(openai_client.clone()))
.then_store_with(
Qdrant::builder()
.batch_size(50)
.vector_size(1536)
.build()?,
)
.run()
.await?;
```
Querying for an example on how to use the query pipeline:
```rust
query::Pipeline::default()
.then_transform_query(GenerateSubquestions::from_client(
openai_client.clone(),
))
.then_transform_query(Embed::from_client(
openai_client.clone(),
))
.then_retrieve(qdrant.clone())
.then_answer(Simple::from_client(openai_client.clone()))
.query("How can I use the query pipeline in Swiftide?")
.await?;
```
Running an agent that can search code:
```rust
#[swiftide::tool(
description = "Searches code",
param(name = "code_query", description = "The code query")
)]
async fn search_code(
context: &dyn AgentContext,
code_query: &str,
) -> Result<ToolOutput, ToolError> {
let command_output = context
.executor()
.exec_cmd(&Command::shell(format!("rg '{code_query}'")))
.await?;
Ok(command_output.into())
}
agents::Agent::builder()
.llm(&openai)
.tools(vec![search_code()])
.build()?
.query("In what file can I find an example of a swiftide agent?")
.await?;
```
_You can find more detailed examples in [/examples](https://github.com/bosun-ai/swiftide/tree/master/examples)_

## Vision
Our goal is to create a fast, extendable platform for building LLM applications in Rust, to further the development of automated AI applications, with an easy-to-use and easy-to-extend api.
<p align="right">(<a href="#readme-top">back to top</a>)</p>
## Features
- Fast, modular streaming indexing pipeline with async, parallel processing
- Experimental query pipeline
- Experimental agent framework
- A variety of loaders, transformers, semantic chunkers, embedders, and more
- Bring your own transformers by extending straightforward traits or use a closure
- Splitting and merging pipelines
- Jinja-like templating for prompts
- Store into multiple backends
- Integrations with OpenAI, Groq, Gemini, Anthropic, Redis, Qdrant, Ollama, FastEmbed-rs, Fluvio, LanceDB, and Treesitter
- Evaluate pipelines with RAGAS
- Sparse vector support for hybrid search
- `tracing` supported for logging and tracing, see /examples and the `tracing` crate for more information.

## Getting Started
### Prerequisites
Make sure you have the rust toolchain installed. [rustup](https://rustup.rs) Is the recommended approach.
To use OpenAI, an API key is required. Note that by default `async_openai` uses the `OPENAI_API_KEY` environment variables.
Other integrations might have their own requirements.
### Installation
1. Set up a new Rust project
2. Add swiftide
```sh
cargo add swiftide
```
3. Enable the features of integrations you would like to use in your `Cargo.toml`
4. Write a pipeline (see our examples and documentation)
<p align="right">(<a href="#readme-top">back to top</a>)</p>
## Usage and concepts
Before building your streams, you need to enable and configure any integrations required. See /examples.
_We have a lot of examples, please refer to /examples and the [Documentation](https://docs.rs/swiftide/latest/swiftide/)_
> [!NOTE]
> No integrations are enabled by default as some are code heavy. We recommend you to cherry-pick the integrations you need. By convention flags have the same name as the integration they represent.
### Indexing
An indexing stream starts with a Loader that emits Nodes. For instance, with the Fileloader each file is a Node.
You can then slice and dice, augment, and filter nodes. Each different kind of step in the pipeline requires different traits. This enables extension.
Nodes have a path, chunk and metadata. Currently metadata is copied over when chunking and _always_ embedded when using the OpenAIEmbed transformer.
- **from_loader** `(impl Loader)` starting point of the stream, creates and emits Nodes
- **filter_cached** `(impl NodeCache)` filters cached nodes
- **then** `(impl Transformer)` transforms the node and puts it on the stream
- **then_in_batch** `(impl BatchTransformer)` transforms multiple nodes and puts them on the stream
- **then_chunk** `(impl ChunkerTransformer)` transforms a single node and emits multiple nodes
- **then_store_with** `(impl Storage)` stores the nodes in a storage backend, this can be chained
Additionally, several generic transformers are implemented. They take implementers of `SimplePrompt` and `EmbedModel` to do their things.
> [!WARNING]
> Due to the performance, chunking before adding metadata gives rate limit errors on OpenAI very fast, especially with faster models like 3.5-turbo. Be aware.
### Querying
A query stream starts with a search strategy. In the query pipeline a `Query` goes through several stages. Transformers and retrievers work together to get the right context into a prompt, before generating an answer. Transformers and Retrievers operate on different stages of the Query via a generic statemachine. Additionally, the search strategy is generic over the pipeline and Retrievers need to implement specifically for each strategy.
That sounds like a lot but, tl&dr; the query pipeline is _fully and strongly typed_.
- **Pending** The query has not been executed, and can be further transformed with transformers
- **Retrieved** Documents have been retrieved, and can be further transformed to provide context for an answer
- **Answered** The query is done
Additionally, query pipelines can also be evaluated. I.e. by [Ragas](https://ragas.io).
Similar to the indexing pipeline each step is governed by simple Traits and closures implement these traits as well.
