gluex-rcdb

Rust bindings for the GlueX Run Condition Database (RCDB). This crate provides a simple interface for loading run conditions from RCDB which match the given context (run numbers and filters). It also provides common aliases used to determine production data.

Installation

cargo add gluex-rcdb

Example

use gluex_core::run_periods::RunPeriod;
use gluex_rcdb::{conditions, RCDBContext, RCDB};

fn main() -> gluex_rcdb::RCDBResult<()> {
    // Uses RCDB_CONNECTION by default; use RCDB::open(...) for explicit paths.
    let rcdb = RCDB::new()?;
    let filters = conditions::aliases::approved_production(RunPeriod::RP2018_08);
    let ctx = RCDBContext::default().with_run_range(55_000..=55_050).filter(filters);
    let rows = rcdb.fetch(["polarization_angle", "polarization_direction"], &ctx)?;

    for (run, values) in rows {
        if let Some(angle) = values
            .get("polarization_angle")
            .and_then(|v| v.as_float())
        {
            println!("run {run}: angle = {angle:.2}");
        }
    }
    Ok(())
}
