Struct DragConstraints 

pub struct DragConstraints {
    pub min_x: Option<f32>,
    pub max_x: Option<f32>,
    pub min_y: Option<f32>,
    pub max_y: Option<f32>,
    pub grid_snap: Option<f32>,
}

Constraints applied to drag position.

Fields

min_x: Option<f32>

Optional minimum x position.

max_x: Option<f32>

Optional maximum x position.

min_y: Option<f32>

Optional minimum y position.

max_y: Option<f32>

Optional maximum y position.

grid_snap: Option<f32>

Optional grid size used to snap both axes.

Implementations

impl DragConstraints

pub fn unbounded() -> DragConstraints

Create unconstrained drag bounds.

pub fn bounded( min_x: f32, max_x: f32, min_y: f32, max_y: f32, ) -> DragConstraints

Create rectangular drag bounds.

pub fn with_grid_snap(self, grid: f32) -> DragConstraints

Add grid snapping.

pub fn constrain( &self, position: [f32; 2], axis: DragAxis, locked_origin: [f32; 2], ) -> [f32; 2]

Apply axis filtering, bounds, and grid snapping.

Trait Implementations

impl Clone for DragConstraints

fn clone(&self) -> DragConstraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DragConstraints

impl Debug for DragConstraints

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

Formats the value using the given formatter.

impl Default for DragConstraints

fn default() -> DragConstraints

Returns the “default value” for a type.

impl PartialEq for DragConstraints

fn eq(&self, other: &DragConstraints) -> 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.
