Determine whether data from different sources are the same.
use std::fs::File;
use same_content::*;
assert!(!same_content_from_files(&mut File::open("tests/data/P1140310.jpg").unwrap(), &mut File::open("tests/data/P1140558.jpg").unwrap()).unwrap());The default buffer size for the same_content_from_files function and the same_content_from_readers function is 256 bytes per stream. If you want to change that, you can use the same_content_from_files2 function or the same_content_from_readers2 function, and define a length explicitly.
For example, to change the buffer size to 4096 bytes,
use std::fs::File;
use same_content::*;
use same_content::generic_array::typenum::U4096;
assert!(!same_content_from_files2::<U4096>(&mut File::open("tests/data/P1140310.jpg").unwrap(), &mut File::open("tests/data/P1140558.jpg").unwrap()).unwrap());You may want to use async APIs with your async runtime. This crate supports tokio, currently.
