Struct InputSnapshot 

pub struct InputSnapshot {
    pub mouse_position: Vector2,
    pub mouse_buttons: IndexSet<MouseButton>,
    pub pressed_keys: IndexSet<KeyboardKey>,
    pub pressed_chars: Vec<char>,
    pub scroll_delta: Vector2,
}

Snapshot of keyboard and mouse state for the current frame.

Fields

mouse_position: Vector2

Cursor position in physical window pixels.

mouse_buttons: IndexSet<MouseButton>

Mouse buttons currently held down.

pressed_keys: IndexSet<KeyboardKey>

Keyboard keys currently held down.

pressed_chars: Vec<char>

Text input characters received this frame (IME preedit).

scroll_delta: Vector2

Scroll wheel delta accumulated this frame (lines or pixels, depending on winit event).
