Struct crossterm_winapi::ButtonState

pub struct ButtonState { /* fields omitted */ }

The status of the mouse buttons. The least significant bit corresponds to the leftmost mouse button. The next least significant bit corresponds to the rightmost mouse button. The next bit indicates the next-to-leftmost mouse button. The bits then correspond left to right to the mouse buttons. A bit is 1 if the button was pressed.

The state can be one of the following:

Release = 0x0000,
/// The leftmost mouse button.
FromLeft1stButtonPressed = 0x0001,
/// The second button from the left.
FromLeft2ndButtonPressed = 0x0004,
/// The third button from the left.
FromLeft3rdButtonPressed = 0x0008,
/// The fourth button from the left.
FromLeft4thButtonPressed = 0x0010,
/// The rightmost mouse button.
RightmostButtonPressed = 0x0002,
/// This button state is not recognized.
Unknown = 0x0021,
/// The wheel was rotated backward, toward the user; this will only be activated for `MOUSE_WHEELED ` from `dwEventFlags`
Negative = 0x0020,
