Enum Reach 

pub enum Reach<S: Scalar> {
    Cone {
        slope: S,
    },
    Tube {
        radius: S,
    },
}

How far from its ray a Pointer reaches: what counts as under it, at any distance along the ray. Everything a viewer draws at a constant size on screen — a handle, a label, a frame datum — is laid out in reaches, so it is hit where it is drawn however far away or zoomed in the view is.

Variants

Cone

Seen in perspective: a cone around the ray, from its origin — the eye — widening by slope per unit of distance.

Fields

slope: S

Tube

Seen orthographically: a tube of radius around the ray.

Fields

radius: S

Implementations

impl<S: Scalar> Reach<S>

pub fn at(&self, t: S) -> S

How far from the ray it reaches, t along it.

Trait Implementations

impl<S: Clone + Scalar> Clone for Reach<S>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Copy + Scalar> Copy for Reach<S>

impl<S: Debug + Scalar> Debug for Reach<S>

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

Formats the value using the given formatter.

impl<'de, S> Deserialize<'de> for Reach<S>

where S: Scalar,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<S: PartialEq + Scalar> PartialEq for Reach<S>

fn eq(&self, other: &Reach<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.

impl<S> Serialize for Reach<S>

where S: Scalar,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
