kdam is a port of tqdm library which is written in python. kdam has almost same features as tqdm with extra features included. kdam is also 4 times faster than tqdm. kdam has only one external dependency which terminal-size.
Instantly make your loops show a smart progress meter. Just wrap any iterator with tqdm!(iterator) macro and you're done!
```rust use kdam::tqdm;
fn main() { for _ in tqdm!(0..100) {} } ```
100%|█████████████████████████████| 100/100 [00:00<00:00, 25854.49it/s]
kdam also supports different animation styles. All available animations styles are:
examples/showcaseanimations.rs
kdam also support rich.progress style bars with customizable columns.
Fira Code is the first programming font to offer dedicated glyphs to render progress bars. kdam has an animation style to support it.
Add this to your Cargo.toml file.

Or add from github main branch.

kdam = { git = "https://github.com/clitic/kdam.git", branch = "main" }
```rust use kdam::tqdm;
fn main() { let chars = ["a", "b", "c", "d"]; let mut charset = String::new();
for i in tqdm!(chars.iter()) {
charset += i;
}
assert_eq!(charset, "abcd");
} ```
```rust use kdam::tqdm;
fn main() { let mut pb = tqdm!(total = 100); for _ in 0..100 { pb.update(1); } } ```
Another example without a total value. This only shows basic stats.
```rust use kdam::tqdm;
fn main() { let mut pb = tqdm!();
for _ in 0..10000000 {
pb.update(1);
}
pb.refresh();
} ```
10000000 [00:03, 2998660.35it/s]
Custom information can be displayed and updated dynamically on kdam bars with the desc and postfix.
```rust use kdam::tqdm;
fn main() { let mut pb = tqdm!(total = 10); pb.refresh();
for i in 0..10 {
std::thread::sleep(std::time::Duration::from_secs_f32(0.5));
pb.set_description(format!("GEN {}", i));
pb.set_postfix(format!("str={}, lst={:?}", "h", [1, 2]));
pb.update(1);
}
} ```

kdam supports nested progress bars. For manual control over positioning (e.g. for multi-processing use), you may specify position=n where n=0 for the outermost bar, n=1 for the next, and so on.
```rust use kdam::tqdm;
fn main() { for _ in tqdm!(0..4, desc = "1st loop".tostring(), position = 0) { for _ in tqdm!(0..5, desc = "2nd loop".tostring(), position = 1) { for _ in tqdm!(0..50, desc = "3rd loop".tostring(), position = 2) { std::thread::sleep(std::time::Duration::fromsecs_f32(0.0001)); } } }
eprint!("{}", "\n".repeat(3));
println!("completed!");
} ```
1st loop: 50%|███████▎ | 2/4 [00:08<00:08, 0.25it/s]
2nd loop: 60%|████████▌ | 3/5 [00:02<00:01, 1.25it/s]
3rd loop: 0%|▎ | 0/50 [00:00<00:00, ?it/s]
Since kdam uses a simple printing mechanism to display progress bars, you should not write any message in the terminal using println!() while a progressbar is open.
To write messages in the terminal without any collision with kdam bar display, a .write() method is provided. This message will print at bar output location, which is stderr by default.
```rust use kdam::tqdm;
fn main() { let mut pb = tqdm!(total = 10);
for i in 0..10 {
std::thread::sleep(std::time::Duration::from_secs_f32(0.1));
pb.update(1);
pb.write(format!("Done task {}", i));
}
} ```
Done task 0
Done task 1
Done task 2
Done task 3
Done task 4
Done task 5
Done task 6
Done task 7
Done task 8
Done task 9

Similarly .input() method can be called to store an user input.
```rust use kdam::tqdm;
fn main() { let mut pb = tqdm!(total = 10);
for i in 0..10 {
if i == 5 {
if pb.input("Break Loop [y/n]: ").unwrap() == "y\r\n" {
break;
}
}
pb.update(1);
}
} ```
Break Loop [y/n]: y
