Procedure allows to execute tasks with a visual indication to the end user in the stdout.
This is inteted to be used as a command line display.
rust
let a = procedure::proceed("Download", "example_file.jpg", |progress| -> Result<&str, &str> {
for _ in 0..100 {
std::thread::sleep(std::time::Duration::from_millis(10));
progress.increment(1);
}
Ok("example_file.jpg [256 KB]")
});
assert_eq!(a.unwrap(), "example_file.jpg [256 KB]");
let b = procedure::proceed("Download", "some_other.zip", |progress| -> Result<&str, &str> {
let min = 500;
let max = 1000;
for i in min..max {
std::thread::sleep(std::time::Duration::from_millis(5));
progress.set_from(min, max, i);
if i == 975 {
return Err("some_other.zip [Failed]");
}
}
Ok("some_other.zip [1 MB]")
});
assert_eq!(b.unwrap_err(), "some_other.zip [Failed]");
