• 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

Quick Example

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(())
}
