# xportrs
**Pure Rust SAS XPORT (XPT) library for CDISC clinical trial data submissions**
[](https://crates.io/crates/xportrs)
[](https://docs.rs/xportrs)
[](https://github.com/rubentalstra/xportrs/actions/workflows/ci.yml)
[](https://deps.rs/repo/github/rubentalstra/xportrs)
[](LICENSE)
[](https://doi.org/10.5281/zenodo.18219718)
A safe, DataFrame-agnostic implementation of SAS Transport v5 (XPT) file I/O with built-in regulatory compliance validation for FDA, PMDA, and NMPA submissions.
## Features
- **Regulatory Compliance** — Built-in validation for FDA, PMDA, and NMPA submission requirements
- **Read & Write** — Full support for SAS Transport v5 format
- **Auto File Splitting** — Automatically splits files exceeding agency size limits (5 GB)
- **Framework Agnostic** — Works with any in-memory data representation
- **Safe by Design** — Zero unsafe code, no C dependencies
## Regulatory Agency Support
| Agency | Region | Character Encoding | Max File Size |
|----------|---------------|--------------------|---------------|
| **FDA** | United States | ASCII | 5 GB |
| **PMDA** | Japan | UTF-8 (Japanese) | 5 GB |
| **NMPA** | China | UTF-8 (Chinese) | 5 GB |
All agencies enforce: 8-byte variable names, 40-byte labels, 200-byte character values.
## Installation
```toml
[dependencies]
xportrs = "0.0.8"
```
## Quick Example
```rust
use xportrs::{Xpt, Agency};
fn main() -> Result<(), xportrs::Error> {
// Read an XPT file
let dataset = Xpt::read("dm.xpt")?;
// Write with FDA compliance validation
Xpt::writer(dataset)
.agency(Agency::FDA)
.finalize()?
.write_path("dm.xpt")?;
Ok(())
}
```
