Implementations

impl Rotation

pub fn degrees(self) -> u16

Trait Implementations

impl Add for Rotation

type Output = Rotation

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for Rotation

fn clone(&self) -> Rotation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rotation

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

Formats the value using the given formatter.

impl PartialEq for Rotation

fn eq(&self, other: &Rotation) -> 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 Sub for Rotation

type Output = Rotation

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl TryFrom<f64> for Rotation

Get rotation from multiples of 90 deg

The given value is rounded to an integer number

assert_eq!(Rotation::try_from(90.).unwrap(), Rotation::_90);
assert_eq!(Rotation::try_from(-90.).unwrap(), Rotation::_270);
assert!(Rotation::try_from(1.).is_err());

type Error = InvalidRotation

The type returned in the event of a conversion error.

fn try_from(value: f64) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Rotation

impl Eq for Rotation

impl StructuralPartialEq for Rotation
