Enum RotationConstraint 

pub enum RotationConstraint<S> {
    None,
    Free,
    Discrete(Vec<S>),
}

Allowed rotation angles for a geometry.

Variants

None

No rotation allowed (fixed orientation).

Free

Free rotation (any angle).

Discrete(Vec<S>)

Discrete rotation steps (e.g., 0, 90, 180, 270 degrees).

Implementations

impl<S: RealField + Copy> RotationConstraint<S>

pub fn axis_aligned() -> Self

Creates a constraint for axis-aligned rotations only (0, 90, 180, 270 degrees).

pub fn steps(n: usize) -> Self

Creates a constraint for n evenly-spaced rotations.

Panics

Panics if n exceeds the precision of the scalar type (unlikely in practice: n > 2^24 for f32, n > 2^53 for f64).

pub fn is_fixed(&self) -> bool

Returns true if no rotation is allowed.

pub fn angles(&self) -> Vec<S>

Returns the list of allowed angles.

Trait Implementations

impl<S: Clone> Clone for RotationConstraint<S>

fn clone(&self) -> RotationConstraint<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for RotationConstraint<S>

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

Formats the value using the given formatter.

impl<S> Default for RotationConstraint<S>

fn default() -> RotationConstraint<S>

Returns the “default value” for a type.

impl<S: PartialEq> PartialEq for RotationConstraint<S>

fn eq(&self, other: &RotationConstraint<S>) -> 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.
