text-parser is a streaming parser for text file based on nom parser combinator.

lib.rs:

Text Reader for large text file.

Example

use gchemol_parser::TextReader;

let mut reader = TextReader::try_from_path("./tests/files/ch3f.mol2".as_ref()).unwrap();

// read a line into `s`
let mut s = String::new();
reader.read_line(&mut s).unwrap();

// seek a specific line
let _ = reader.seek_line(|line| line.starts_with("@<TRIPOS>")).unwrap();

// split remaining text into chunks (each chunk has 5 lines)
let chunks = reader.chunks(5);

for x in chunks {
    // call nom parser to parse each chunk
    dbg!(x);
}
