With readcon-core

core parses and writes one stream or file. db keeps thousands of those frames, indexes them, and lets many readers mmap the same tree. CON text stays authoritative.

Open, ingest, select

use readcon_db::{ConCorpus, Select};

let db = ConCorpus::open("/tmp/corpus")?;
db.append_trajectory_path(1, "run.con")?;
let keys = db.select(&Select::new().require_symbol("Cu"))?;
let h = db.frame_hash(keys[0])?;

C, Python, Fortran

C / C++: include/readcon-db.h – rkrdb_* and RAII readcon_db::Corpus. MPI: readcon-db-mpi.h takes the caller communicator.
Python: maturin develop --features python → readcon_db.ConCorpus.
Fortran: fortran/ReadConDb with bind(C) helpers.
