Crate las_rs 

las_rs — a high-performance parser and writer for LAS (Log ASCII Standard) well-log files, supporting LAS 1.2, 2.0, and 3.0.

The crate is pure Rust by default. The optional python feature adds the PyO3 bindings that back the las-rs PyPI wheel; Rust consumers never pull PyO3 or numpy.

Quick start

// Read from disk (encoding auto-detected).
let las = las_rs::read_file("welllog.las")?;

// Header metadata.
println!("well: {:?}", las.well_value("WELL"));
println!("index unit: {:?}", las.index_unit);

// Curve data (NULLs are NaN).
for name in las.curve_mnemonics() {
    let n = las.curve_data(name).map_or(0, |d| d.len());
    println!("{name}: {n} samples");
}

Parse from a string with parse, or take full control of parsing via ReadOptions + parse_with / read_file_with.
