Rust bindings for [RayforceDB](https://core.rayforcedb.com), a high-performance columnar
database designed for analytics and data operations. The core is written in pure C with
minimal overhead — combining columnar storage with SIMD vectorization for lightning-fast
analytics on time-series and big-data workloads.

The bindings call the core's C API **directly** (no marshalling shim), so reads are
zero-copy where it counts: a numeric column is exposed as a `&[T]` slice rather than
copied element by element.

**Full Documentation:** https://rs.rayforcedb.com/

## Features

- **Fluent API** — chainable, intuitive query builders that read like the operation; real
  operator overloads for arithmetic, methods for comparisons.
- **Zero-Copy & High Performance** — build a column in a single `memcpy`, read it back as a
  borrow; minimal overhead between Rust and the RayforceDB runtime via the C API.
- **Type-Safe** — a full value model (atoms, vectors, lists, dicts, tables) with
  `ToValue`/`FromValue` conversions and optional `chrono` temporals.
- **Lightweight** — the core is less than a 1 MB footprint.
- **Batteries included** — CSV & splayed I/O, binary serialization, and a TCP/IPC client.

## Quick Start

```rust
use rayforce::{col, Runtime, Table, Value};

let _rt = Runtime::new()?;                       // one live runtime per process

let quotes = Table::new(
    &["symbol", "bid", "ask"],
    &[
        Value::sym_vec(&["AAPL", "AAPL", "AAPL", "GOOG", "GOOG", "GOOG"]),
        Value::vec(&[100.0f64, 101.0, 102.0, 200.0, 201.0, 202.0]),
        Value::vec(&[110.0f64, 111.0, 112.0, 210.0, 211.0, 212.0]),
    ],
)?;

let result = quotes
    .select()
    .agg("max_bid", col("bid").max())
    .agg("min_bid", col("bid").min())
    .agg("avg_ask", col("ask").avg())
    .agg("count",   col("bid").count())
    .filter(col("bid").ge(110.0).and(col("ask").gt(100.0)))
    .by("symbol")
    .execute()?;

println!("{result}");
```

```text
┌────────┬─────────┬─────────┬─────────┬───────┐
│ symbol │ max_bid │ min_bid │ avg_ask │ count │
│  SYM   │   F64   │   F64   │   F64   │  I64  │
├────────┼─────────┼─────────┼─────────┼───────┤
│ GOOG   │ 202.0   │ 200.0   │ 211.0   │ 3     │
├────────┴─────────┴─────────┴─────────┴───────┤

└──────────────────────────────────────────────┘
```

## Installation

The crate links two local checkouts: the RayforceDB **core** (`RAYFORCE_SRC`) and the
**rayforce-q** IPC client (`RAYFORCE_Q_SRC`). The build script compiles both and statically
links `librayforce.a`.

```toml
# Cargo.toml
[dependencies]
rayforce = { git = "https://github.com/RayforceDB/rayforce-rs" }
```

```sh
git clone https://github.com/RayforceDB/rayforce   ~/rayforce      # core
git clone https://github.com/RayforceDB/rayforce-q ~/rayforce-q    # Q IPC client

export RAYFORCE_SRC=/path/to/rayforce       # default: ~/rayforce
export RAYFORCE_Q_SRC=/path/to/rayforce-q   # default: ~/rayforce-q

cargo build
cargo test
```

Requirements: a C toolchain (`make`, `clang`) and `libclang` for `bindgen`.

`bindgen` locates `libclang` via `LIBCLANG_PATH`. This is deliberately **not** set in the
repo's `.cargo/config.toml`. If bindgen can't auto-detect libclang, set it yourself:

```sh
# macOS (CTL):
export LIBCLANG_PATH="/Library/Developer/CommandLineTools/usr/lib"
# Linux:
export LIBCLANG_PATH="$(dirname "$(find /usr/lib -name 'libclang*.so*' | head -1)")"
```

The `chrono` is on by default for date/time/timestamp conversions.
