Struct Interaction 

pub struct Interaction {
    pub event: Option<Event>,
    pub press: Option<Press>,
    pub text: Option<TextOutcome>,
    pub escape_pressed: bool,
    pub delete_pressed: bool,
    pub shift: bool,
}

Per-frame input state passed to the canvas drawing closure.

event holds the mouse/pointer interaction (if any) with all positions already converted to world space. The boolean flags fire independently — a key press and a mouse event can both be set in the same frame.

Fields

event: Option<Event>

press: Option<Press>

The primary button’s press in progress, present exactly while the button is held. Level-triggered, unlike event: press-and-hold affordances (route-start targets, new-pin markers) read it every frame, where the edge events only report the gesture’s resolution.

text: Option<TextOutcome>

How the in-place editor the tool opened ended, if it did this frame: the edited text on a commit or a Tab, or a cancel.

escape_pressed: bool

Escape was pressed while the canvas held keyboard focus. Cancels a gesture in progress.

delete_pressed: bool

Delete or Backspace was pressed while the canvas held keyboard focus.

shift: bool

Shift was held this frame — extends a selection (shift-click / shift-marquee).

Trait Implementations

impl Clone for Interaction

fn clone(&self) -> Interaction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Interaction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Interaction

fn eq(&self, other: &Interaction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
