Struct GCQuaternion

#[repr(C)]
pub struct GCQuaternion {
    pub x: c_double,
    pub y: c_double,
    pub z: c_double,
    pub w: c_double,
}

Available on crate feature GCMotion only.

Represents a quaternion (one way of parameterizing attitude). If q is an instance of GCQuaternion, mathematically it represents the following quaternion:

q.xi + q.yj + q.z*k + q.w

Trait Implementations

impl Clone for GCQuaternion

fn clone(&self) -> GCQuaternion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GCQuaternion

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

Formats the value using the given formatter.

impl Encode for GCQuaternion

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for GCQuaternion

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

impl RefEncode for GCQuaternion

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Copy for GCQuaternion

impl StructuralPartialEq for GCQuaternion
