Enum HandleDrag 

pub enum HandleDrag {
    Rotate {
        ring: Ring,
        grab: Vec3,
    },
    Translate {
        shaft: Shaft,
        grab: f32,
    },
}

Anchored at the press, so a widget following the subject does not chase its own drag.

Implementations

impl HandleDrag

pub fn press( handle: Handle, ray_origin: Vec3, ray_direction: Vec3, ) -> Option<Self>

pub fn id(&self) -> HandleId

pub fn delta( &self, ray_origin: Vec3, ray_direction: Vec3, ) -> Option<TransformDelta>

None when the ray cannot be read against the handle; callers hold the last delta.

Trait Implementations

impl Clone for HandleDrag

fn clone(&self) -> HandleDrag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandleDrag

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

Formats the value using the given formatter.

impl PartialEq for HandleDrag

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