Struct Spinner 

pub struct Spinner { /* private fields */ }

A simple terminal spinner that runs in a background thread

The spinner automatically stops and cleans up when dropped, making it safe to use in code paths that may error or panic.

Example

use cascade_cli::utils::spinner::Spinner;

let mut spinner = Spinner::new("Loading data".to_string());
// ... do some work ...
spinner.stop_with_message("✓ Data loaded");

Implementations

impl Spinner

pub fn new(message: String) -> Self

Start a new spinner with the given message

The spinner will animate in a background thread until stopped.

pub fn new_with_output_below(message: String) -> Self

Start a new spinner that stays on one line while content appears below

This variant prints the message with a newline, then updates only the spinner character using ANSI cursor positioning. Content can be printed below without being overwritten by the spinner.

pub fn stop(&mut self)

Stop the spinner and clear the line

This method is idempotent - it’s safe to call multiple times.

pub fn stop_with_message(&mut self, message: &str)

Stop the spinner and replace with a final message

This is useful for showing success/failure status after completion.

pub fn update_message(&mut self, new_message: String)

Update the spinner’s message while it’s running

Note: This creates a brief flicker as we stop and restart the spinner. For frequent updates, consider using stop_with_message() instead.
