-Benutzereingabe 1 von 2 - 5.6.2025, 02:27:36:
-in Rust, what can I use to display multiple progress bars in the terminal?
-
-o3-mini:
-You can use the indicatif crate, which provides a MultiProgress type that lets you manage and display multiple progress bars concurrently in a terminal.
-
-Below is a simple example of how to use indicatif’s MultiProgress to display multiple progress bars:
-
-```rust
-use indicatif::{MultiProgress, ProgressBar, ProgressStyle};
-use std::{thread, time::Duration};
-
-fn main() {
-    // Create a MultiProgress container.
-    let m = MultiProgress::new();
-
-    // Create several progress bars.
-    let pb1 = m.add(ProgressBar::new(100));
-    pb1.set_style(
-        ProgressStyle::default_bar()
-            .template("{msg} {bar:40.cyan/blue} {pos:>3}/{len:3}")
-            .expect("Failed to set progress bar style"),
-    );
-    pb1.set_message("Downloading");
-
-    let pb2 = m.add(ProgressBar::new(50));
-    pb2.set_style(
-        ProgressStyle::default_bar()
-            .template("{msg} {bar:40.green/black} {pos:>3}/{len:3}")
-            .expect("Failed to set progress bar style"),
-    );
-    pb2.set_message("Processing");
-
-    // Optionally, spawn threads to update the progress bars concurrently.
-    let h1 = std::thread::spawn(move || {
-        for i in 0..=100 {
-            pb1.set_position(i);
-            thread::sleep(Duration::from_millis(50));
-        }
-        pb1.finish_with_message("Download complete");
-    });
-
-    let h2 = std::thread::spawn(move || {
-        for i in 0..=50 {
-            pb2.set_position(i);
-            thread::sleep(Duration::from_millis(100));
-        }
-        pb2.finish_with_message("Processing complete");
-    });
-
-    // Wait for threads to complete. MultiProgress takes care of rendering.
-    h1.join().expect("Thread 1 panicked");
-    h2.join().expect("Thread 2 panicked");
-
-    // You may also iterate on the multi-progress which blocks until all bars finish:
-    // m.join().unwrap();
-}
-```
-
-### Steps Explained
-
-1. **MultiProgress Container**:  
-   Create a `MultiProgress` instance which is used to manage multiple progress bars.
-
-2. **Progress Bars**:  
-   Create individual progress bars using `MultiProgress::add()`. You can customize each progress bar with a message, style, and length.
-
-3. **Concurrent Updates**:  
-   The example spawns two threads – one for each progress bar. Each thread updates its progress bar independently using `set_position()` and finishes the progress bar with `finish_with_message()`.
-
-4. **Thread Joining**:  
-   Ensure the main thread waits for the worker threads to complete to prevent the program from exiting prematurely.
-
-### Installation
-
-Make sure to add indicatif to your Cargo.toml:
-
-```toml
-[dependencies]
-indicatif = "0.17"  # or the latest version available on crates.io
-```
-
-This crate provides many options for customizing and using progress bars in a concurrent and effective manner. The documentation is available at [indicatif on docs.rs](https://docs.rs/indicatif) for further details and advanced usage.
