|

///
|
||
/// Every time the user touches the screen, a new [`TouchPhase::Started`] event with an unique
|
||
/// identifier for the finger is generated. When the finger is lifted, the [`TouchPhase::Ended`]
|
||
/// event is generated with the same finger id.
|
||
///
|
||
/// After a [`TouchPhase::Started`] event has been emitted, there may be zero or more [`TouchPhase::Moved`]
|
||
/// events when the finger is moved or the touch pressure changes.
|
||
///
|
||
/// The finger id may be reused by the system after an [`TouchPhase::Ended`] event. The user
|
||
/// should assume that a new [`TouchPhase::Started`] event received with the same id has nothing
|
||
/// to do with the old finger and is a new finger.
|
||
///
|
||
/// A [`TouchPhase::Canceled`] event is emitted when the system has canceled tracking this
|
||
/// touch, such as when the window loses focus, or on iOS if the user moves the
|
||
/// device against their face.

||
///
|
||
/// ## Note

/// This event is the translated version of the `WindowEvent::Touch` from the `winit` crate.

/// It is available to the end user and can be used for game logic.
