A loading spinner widget that animates through symbol sets.

Uses the throbber-widgets-tui Rust crate for rendering. The caller controls the animation by incrementing the :step value (typically on each tick or timer event).

Animation sets

The :throbber_set option selects the symbol animation:

• :braille (default) — braille dot patterns (⠷ ⠯ ⠟ ⠻ ⠽ ⠾)
• :dots — braille double dots
• :ascii — classic spinner (| / - )
• :vertical_block — growing vertical block (▁ ▂ ▃ … █)
• :horizontal_block — growing horizontal block (▏ ▎ ▍ … █)
• :arrow — rotating arrow (↑ ↗ → ↘ ↓ ↙ ← ↖)
• :clock — clock emoji animation
• :box_drawing — box-drawing rotation
• :black_circle — rotating black circle
• :white_circle — rotating white circle
• :white_square — rotating white square
• :quadrant_block — quadrant block rotation
