Struct trackball::Scale

pub struct Scale<N: Copy + RealField> { /* private fields */ }

Scale induced by relative input.

Implements Default and can be created with Scale::default().

Implementations

impl<N: Copy + RealField> Scale<N>

pub fn compute(&self, num: N) -> N

Computes scale ratio from relative value.

pub const fn denominator(&self) -> N

Denominator. Default is scroll unit of 120.0.

pub fn set_denominator(&mut self, den: N)

Sets denominator. Default is scroll unit of 120.0.

pub fn cast<M: Copy + RealField>(self) -> Scale<M>where N: SubsetOf<M>,

Casts components to another type, e.g., between f32 and f64.

Trait Implementations

impl<N: Clone + Copy + RealField> Clone for Scale<N>

fn clone(&self) -> Scale<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Debug + Copy + RealField> Debug for Scale<N>

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

Formats the value using the given formatter.

impl<N: Copy + RealField> Default for Scale<N>

fn default() -> Self

Returns the “default value” for a type.

impl<N: PartialEq + Copy + RealField> PartialEq<Scale<N>> for Scale<N>

fn eq(&self, other: &Scale<N>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
