Function read_from_file

pub fn read_from_file<F>(
    magic_bytes: &[u8],
    window_size: i64,
    input: &mut F,
) -> Result<Vec<u8>>
where
    F: Seek + Read,

Allows for reading for configuration from the end of a file by looking for magic bytes

Example

use catconf::read_from_file;

let conf = read_from_file(b"CATCONF", 2048, &mut input)?;
