    Deg0,
    Deg90,
    Deg180,
    Deg270,
}

Display rotation.

Variants

Deg0

Deg90

90° clockwise rotation.

Deg180

180° clockwise rotation.

Deg270

270° clockwise rotation.

Implementations

impl Rotation

pub const fn degree(self) -> i32

Returns the rotation in degrees.

pub const fn try_from_degree(angle: i32) -> Result<Self, InvalidAngleError>

Converts an angle into a rotation.

Returns an error if the angle isn’t an integer multiple of 90°.

pub const fn rotate(self, other: Rotation) -> Self

Rotates one rotation by another rotation.

pub const fn is_horizontal(self) -> bool

Returns true if the rotation is horizontal (0° or 180°).

pub const fn is_vertical(self) -> bool

Returns true if the rotation is vertical (90° or 270°).

Trait Implementations

impl Clone for Rotation

fn clone(&self) -> Rotation

Returns a duplicate of the value.

const 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 Hash for Rotation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Rotation

fn cmp(&self, other: &Rotation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Rotation

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

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

const 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 PartialOrd for Rotation

fn partial_cmp(&self, other: &Rotation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
