Crate nxs 

nxs — the Nyxis binary format library.

Compiles .nxs source text to .nxb binary files and provides a zero-copy query reader for those files.

Quick start

// Compile .nxs source to bytes
let bytes = nxs::compile_source("r0 { id: =1 score: ~9.5 }").unwrap();

// Query the result
use nxs::query::{Reader, eq};
let reader = Reader::new(&bytes).unwrap();
for rec in reader.where_pred(eq("id", 1i64)) {
    println!("{:?}", rec.get_f64("score"));
}
