Function pad_lines 

pub fn pad_lines(pdb_f: &str) -> BufReader<Cursor<Vec<u8>>>

Reads a text file specified by pdb_f, pads each line that starts with ATOM to 80 characters with spaces, and returns a buffered reader over an in-memory buffer containing the padded content.

Arguments

• pdb_f - A string slice that holds the path to the input text file.

Returns

A BufReader wrapped around a Cursor<Vec<u8>>>, where each line from the input file is padded to 80 characters with spaces and newline character.

Panics

This function panics if it encounters any I/O errors while reading or processing the file.

Examples

use pdb_handler::pad_lines;
use std::io::Read;
use std::io::BufReader;

let mut padded_reader = pad_lines("example-pdbs/dna.pdb");
let mut buffer = String::new();
padded_reader.read_to_string(&mut buffer).unwrap();
println!("Padded content:\n{}", buffer);

This example reads lines from “dna.pdb”, pads each line that starts with ATOM with spaces to reach 80 characters, and then prints out the padded content.
