Enum AppEvent 

pub enum AppEvent {
    Key(KeyEvent),
    Resize(u16, u16),
    Tick,
    Market(MarketUpdate),
    ReplaySeek(SeekTo),
    ReplayControl(ReplayControl),
    BundleLoaded(BundleLoadResult),
}

Every input to the synchronous render loop, as one closed set (§4).

Matched exhaustively with no wildcard arm, so a new variant forces every fold site — notably App::on_event — to be revisited by the compiler.

The Market variant is far larger than the input/tick variants, but it rides the hot fan-in path: boxing it would add a heap allocation per quote/Greek update — exactly what the bounded coalescing channel (#10) exists to avoid (docs/06-performance.md). The transient over-allocation is bounded by the channel capacity and small, so the documented unboxed shape (§4) is kept.

Variants

Key(KeyEvent)

A crossterm key press, from the dedicated terminal-input reader task.

Resize(u16, u16)

The terminal was resized to (columns, rows).

Tick

The render/animation cadence fired (default ~250 ms).

Market(MarketUpdate)

A normalized provider update to fold into the live chain store (§4).

ReplaySeek(SeekTo)

A replay-timeline scrub, in replay mode only (docs/04-replay-mode.md §4). Folds directly into the in-memory timeline cursor (the whole bundle is loaded, #33), so it performs no I/O.

ReplayControl(ReplayControl)

A replay playback control (play/pause/speed), in replay mode only (docs/04-replay-mode.md §4). Folds into the Playback state; the tick timer advances the cursor while playing.

BundleLoaded(BundleLoadResult)

The result of the off-thread replay-bundle load (loaded or failed), delivered by the replay load worker (docs/04-replay-mode.md §3, docs/02-tui-architecture.md §12). Folds the replay BundleLoad state machine from Loading to Ready or Error; the render loop never blocks on the load.
